Young's modulus Essays

statistical analysis tests, both the Young’s modulus and elastic toughness had a significant value of less than 0.05. The null hypothesis was then rejected, confirming that our data was acceptable. After comparing the Young’s modulus and elastic toughness of neoprene and silicone to skin, it was determined that silicone would make the best skin substitute. Skin has a Young’s modulus of 0.05 to 3.51 MPa [2]. Based on the data found in the experiment, silicone has a Young’s modulus of 2.183 ± 0.654 MPa while

My Hair Page 1 of 3 Throughout my life, Ive always had a companion by my side, through thick and thin, through the good and the bad, forever growing and changing as I have. I am referring to none other then my hair, and everyone values their hair differently, and no two beings hair is the same, nor will their hair go through the same changes. Isnt hair just a human body feature? Hair is something far more than a body feature it is a depiction of fashion sense, your identity, ethnicity, gender, personality

materials. For compression, we determined the ultimate strength, toughness, elasticity, and Young’ modulus for the almond, brazil nut, pecan, walnut, and hazelnut shells using a material testing apparatus. Properties were recorded in both intact and fragmented forms. This procedure allows us to see if the intact shell properties directly reflect the ultimate strength, toughness, elasticity, and Young’ modulus of the materials that make up the shell or if the structure shell itself plays a bigger role.

Introduction: The objective for the lab was to determine properties of materials by using a tension test. The properties that were determined was Young’s Modulus, ultimate tensile strength, and yield strength. Three aluminum alloys were tested. The first was the AA 2024 , which is high strength used in aerospace applications. The second specimen was AA 5052, which had low strength, but high ductility. The last specimen used was AA 6061, which has moderate strength and is highly resistant to corrosion

aluminium alloy would then fracture. Aluminium alloy has the highest Young's modulus compare to the other 2 specimens. -40-200204060801001201401600 0.05 0.1 0.15 0.2 0.25Stress (MPa)StrainoffsetAlAlloy Polystyrene (PS) Polystyrene undergoes elastic deformation with little plastic deformation before experiencing a brittle fracture as seen on the graph. This is due the high young's modulus polystyrene has, as it has a benzene-ring side group that forms strong

difference to consider is the Young’s modulus of the nerve and the electrode. The electrode, which is made from polysilicon, has a Young’s modulus of around 155 GPa1 while the nerve itself has a Young’s modulus of around 580 kPa2. A large mismatch in Young’s modulus can lead to the electrode being encapsulated by non-neuronal cells as the body attempts to minimize the damage caused by having something stiff inserted into soft tissue. The difference in Young’s modulus interferes with the

3.1. Sample Alteration Both types of shale rock consist on a broad scale quartz, feldspar, plagioclase, calcite, dolomite, pyrite, chlorite, kaolinite, and illite. Marcellus shale has long been known as a major source rock, while Pottsville shale is potential caprock for CO2 storage. X-ray diffraction (XRD) experiments were conducted on both shale samples by Olabode and Radonjic for the compositional data. Comparing the source rock and caprock, both rocks has similar tectosilicates content (quartz

combinations will have an effect on the modulus of the material due to the differences in mesh structure. Unlike part 1, part 2 focuses on variation in mesh structure due to the polymerization of 2, 4, and 8 arm PEGnorb with 2 and 4 arm PEG thiol, rather than the impact of polymerization time. Table II displays the precursor combinations, the resulting hydrogel modulus, and the mesh size of experimental groups 1-2, 4-5, and 7-8. Figure 2 (a) and (b) display the modulus of each group and the mesh size of

mass of the skeleton. Cancellous bone aften reduces the trembling activity (or) we can say it tries to decrease the tremors in the human body. The youngs modulus of the spongy bone is less when compared to the compact bone. The femoral head has smooth covering of cartilage because of the properties of compact bone . Matches the graded modulus of the spongy bones which forms the articulating surface. Actually bones are composite materials which are composed of matrix of collagen fibers, impregnated

is applied to the center of an object while it is supported on each side. This experiment was performed to record each material's flexural behavior so applications can be made with appropriate materials. The objective was to calculate the elastic modulus for each material tested. II. Methodology To start the lab, one measures and records the height and width of the Rectangular Bar specimens (steel, aluminum, sawbones) and the diameter of the Cylindrical specimens (Birch, oak dowel, acrylic, glass)

Bone is one of the most important connective tissues found in the body. It is very intricate, complex and specialised. In addition to providing mechanical support, bone also acts as a reservoir for minerals, mainly calcium and phosphate. The tissue in itself is highly dynamic as it possesses a self-remodelling nature that allows the bone remodel itself depending upon the mechanical loading it encounters, moreover bone can also self-regenerate to a large extent that allows repairing of tissue without

Once the true stress-strain curves were developed from the data extrapolated by the tensile tester, mechanical properties of each metal were compared. 316 Stainless Steel yielded the highest toughness, tensile strength, and percent elongation. For application purposes, environments that entail high impact load, like jet engine components or heat exchangers, are suggested for 316 Stainless Steel. Additionally, as a result of the corrosion resistant properties, 316 Stainless Steel is suggested in environments

three weeks that I spent on campus, I worked with other students to explore all types of engineering from civil to financial. During our largest project of the camp, my group had to measure the tensile strength of different spaghetti and find the young’s modulus, then use that data, along with our new knowledge of vector physics, to create a bridge out of spaghetti that could hold the most weight. My group performed the best out of all the groups because I lead my group to draw inspiration from other

Review of Carbonaceous Grain Formation Introduction: Carbon is produced in red giant stars and supernovae because of triple alpha reactions that occur when 3 alpha particles(He-4) fuse together. The rate that this happens is dependent on the temperature and density. When the distance between particles increases the rate of reaction decreases [1]. After a star cools the carbon begins to collect in the photosphere condensing and forming microstructures with graphene cores. The droplets conglomerate

Abstract— The main aim is to develop the three dimensional solid finite element model of knee joint to predict stress in its individual components (Femur, Tibia, Menisci and Patella) and to determine the load carried by a pre – selected ligamentous tissue. This work assists to analyze a knee response to a dynamically applied load. This simulated analysis will serve to be an alternative approach to destructive tests and intrusive procedures and helps to achieve closer simulation to reality. The main

1. INTRODUCTION One of the actual problems in the manufacturing engineering is related to the assembly of the sheet metals, thin-walled tubes or profiles. These tasks could be performed using Friction Drilling technology, which enable to simplify assembly process and to improve reliability of the joint. Friction drilling is also called Thermal Drilling, Flow Drilling, Form Drilling, or Friction Stir Drilling. Friction drilling is a non-traditional hole-making method that utilizes the heat generated
