Factors That Lead Mechanical Properties - 1109 Words

R L Timings describes materials as being a vital part of the evolution of mankind. He stated that our ability to use and develop materials to satisfy a human requirement is what really set us apart from other animals. This started from building weapons by manipulating stone and wood to hunt and defend territory. He goes on to say this lead to building tools to cultivate land and to manufacture artefacts such as cooking utensils. He finishes this part of his writing by listing how materials have developed for today’s uses including housing, transportation medical care and defence for example. This evolution is down to our ever growing knowledge of a materials property’s .There are a vast range of materials in the world of engineering. Each material has physical and mechanical properties that fits them to a specific engineering task. To understand these products we need to understand the materials molecular structure and how engineering processes effect the structure of t hese materials and in turn effect their properties. In this essay I will be discussing factors effecting mechanical properties, what heat treatment is and why it is used in industry? I will then go into further detail on heat treatment techniques. I will then look into polymers, the two main types of plastics and look into polymer chains and their effect on the materials properties. Then final segment of this text will discuss properties of composite materials and how the structure can influence the propertiesShow MoreRelatedResults And Discussion On Weight Loss1734 Words   |  7 Pagesweight (0- 4.5%). Rather, there are several mechanisms while the change in their relative importance as both the weight % of nano ceramic particles was varied and the applied load were changed (mechanical stress). The main factors controlling the importance of the underlying mechanisms are the mechanical stress, temperature, oxidation phenomenon, and ceramic particle weight %. Considering all such consideration are essential in understanding the sliding wear of metals, it must also be appreciatedRead MoreThe Structural Foundation For The Human Body1648 Words   |  7 Pageshealthy, an individual is able to be very physical and active and exert large forces on their body because the bone can handle it. When bones are weakened either through fracture or disease, bodily mechanical function is reduced dramatically. With this said, Osteoporosis can have a large effect on the mechanical strength of bone. Osteoporosis is very common and about 54 million Americans suffer from it. All of these people are at risk of fracturing bones and have reduced physical ability. The mostRead MoreA Study Of Aneurysm Pathogenesis And Progression1256 Words   |  6 Pagesproviding an- swers to the following questions [12]: 1.

Because of the beneficial properties of ceramics, they were also used for the acetabular cups but these suffered from early failures due to the low fracture toughness. Concerns regarding the low fracture toughness of the ceramic can be addressed by lowering the grain size, lowering the porosity and using different manufacturing techniques like Hot Isostatic Pressing. Carbons, especially pyrolytic carbon, have been used extensively as the leaflets in mechanical heart valves. Carbons were chosenRead MoreIs Bamboo A Sustainable Alternative Building Material For Light Weight Construction?1703 Words   |  7 Pagesbamboo? 1.4 Objectives of the study To recognize the characteristics of bamboo that makes it sustainable. To identify the ability of bamboo to be one of the sustainable alternative building materials in Southeast Asia. To compare the sustainability properties between bamboo and timber material for construction. 1.5 Scope of the study 　　　　This research will be conducted covering low rise buildings and lightweight constructions that is constructed in Southeast Asia. 1.6 Significant of the study 　　　　ThisRead MoreThe Synthesis And Fabrication Of Conductive Polymers Essay1342 Words   |  6 Pagesand vagal nerve stimulators [1]. Conductive polymers are currently being investigated as a promising tool in biomedical applications. Due to their relative ease of synthesis the physiochemical properties of CPs are easily modified to fit different medical needs. Techniques for modifying the properties are surface functionalization or by trapping dopants into the scaffold [4]. the Although there has been a lot of progress in the development of CPs there are still many challenges in creating clinicallyRead MoreMechanotransduction, which is the process by which cells converts mechanical stimuli to biochemical1700 Words   |  7 PagesMechanotransduction, which is the process by which cells converts mechanical stimuli to biochemical signaling cascades, is involved in the homeostasis of numerous tissues. The mechanotransduction of oscillatory shear stress by bone resident cells has gained special attention because of its role in regulating bone formation, remodeling and disease. Mechanical forces, especially, fluid she ar stress has been observed to induce several cellular responses in osteoblastic cells, including intracellularRead MoreTypes Of Polymeric Materials Which Have Hydrocarbon As Its Backbone And Pendent Acid Groups1602 Words   |  7 Pagesgroups leads improvement in properties of polymers like tear resistance, abrasive resistance tensile strength and impact strength.This types of self healing materials can be used in wide variety of application such as membrane separation, automobile parts, roofing materials, coatings, food packaging.

Standardizations done for the synthesis of optimum concentrations of Gelatin and glutaraldehyde required is given in Table 1.1. Gels with low gelatin concentrations were fragile and had low mechanical strength. Concentration of gelatin was optimized to be 5% which satisfied the properties of an ideal scaffold for skin tissue engineering.
