  • Parana Pine: An Analysis Of Young's Modulus Value

    77 E/GPa compared with all the other materials used. Steel is a metal, so it is made up of metallic bonds, which means that the element largely consists of positive ions (positive charge) and delocalized electrons (free electrons of negative charge), the repulsion is balanced within the atom, a main reason to why metals are non-reactive to other elements. However one disadvantage of the using steel is because it consists of iron atoms. Iron is reactive to both water and oxygen, and when these elements react together it forms –iron oxide (rust). Rust can reduce the effectiveness and efficiency of the material. So you should be very careful whilst handling steel in construction. Moreover, metallic bonds have a simple crystal lattice in solid state and are the weakest primary chemical bonds. Hence the reason to why pure metals are dissolved with other elements such as: carbon for mild steels. Metal alloys have increased strength and hardness. The structure of alloys reduces the space between each ion, so there is less space for delocalized electrons and it improves the chemical bond with each element within the…

  • The Monotonic And Axial Stress-Strain Responses Of Fists

    Fig. 5 shows the monotonic and cyclic stress-strain responses of selected specimens having all influential parameters considered in this study, such as the volumetric ratio of transverse steel reinforcement, number of CFRP layers, and aspect ratio. In this figure, the axial stress was calculated by dividing the axial load to the column cross-sectional area, and the corresponding axial strain was derived from the average readings of the four LVDTs divided by the central gauge length of each…

  • Analysis Of Durometer Hardness

    dimensions are 10 mm × 10 mm × 55 mm and V- notch made at angle of 45° with a depth of 2 mm then the experiment was done and values were tabulated. 3.3 SHORE DUROMETER HARDNESS STRENGTH Hardness was defined as materials resisting property to prevent permanent indentation. Durometer is a measure of hardness in polymers, fibre and rubbers where it measures the indentation depth in the material. According to ASTM D2240 tests were conducted on specimen using Durometer in the room temperature [5].…

  • Stodal Analysis Of Mono Goal Leaf Spring

    CHAPTER- 5 ANALYSIS OF STEEL LEAF SPRING ________________________________________________________________ The aim of this analysis is to study the multi-leaf steel leaf spring under loading conditions and verify those results within the allowable limits. ANSYS software is used to analyze the stresses and strains by performing static analysis for the given leaf spring specifications and modal analysis is performed to determine the natural frequencies and mode shapes to asses the behavior of the…

  • Sheet Metal Case Study

    reliable model to analyze dependency of FLDs on grain size, spatial distribution of grains, texture evolution, number of grains, second phase particles (Inal et al., 2002; Inal et al., 2002; Wu et al., 2004; Hu et al., 2008). Although the CP-FEM is a very popular and widely used approach to deal with crystal plasticity (CP) polycrystal modeling, yet it is limited by the large number of degrees of freedom required by CP-FEM computations as well as by the problem of element distortion due to…

  • Analysis Of The Stress Concentration Experiment

    The aim of the Stress Concentration Experiment was to observe the stress concentration factor/feature for a set of mild steel specimens with various irregularities in each sample. These irregularities or “stress-raisers” include any notches and holes which vary in size (radius) and placement on the specimen (edge notches or holes) that may have an effect on the flow of stress. With the use of a Hounsfield 50 kN electrically operated tensile testing machine and 12 1-mm thick mild steel test…

  • The Importance Of Resistance Training

    INTRODUCTION It has been widely accepted that resistance training can be of great value for optimizing health and longevity. Resistance training is designed to improve muscular fitness by exercising a muscle group against an external resistance. Although resistance training is often associated with strength and power sports, this type of training is important in building up specific strengths in all sport categories. With the appropriate training methods, resistance training can enhance an…

  • Bernoulli-Euler Beam Theory

    The overall objective of this lab was to verify Bernoulli-Euler beam theory for the lip-loaded cantilever and use that to calculate the Poisson ratio for the material in this case 6061-T6 aluminum. This was done by having to different objectives for each part of the Lab. Part one was use electrical resistance strain gage, this was to measure the strain a cantilever beam as it undergoes a known deflection. We would then compare the measurements with that of the strains predicted by simple beam…

  • Precipitation Reaction Lab Report

    Precipitation reaction, or otherwise known as double-replacement reaction, is one of the three common types of chemical reactions along with decomposition and combustion. A simple definition for the precipitation reaction would be “atoms from two different compounds switch places” (Lew 40). This means that one of the reactant’s molecule “trades” places with another from another compound to form products, like a precipitate, hence the term double-replacement. A precipitate is usually a solid…

  • Biaxial Tensile Test

    Data Analysis Biaxial Tensile Tests Different stress and strain definitions have been used to study the biomechanics of soft tissue [24]. The 2nd Piola-Kirchhoff stress and Green strain definitions have been employed in this study, which are described briefly in the following. The Green strain tensor is defined as E=1/2(F^T F-1), where F is the gradient deformation tensor. For the case of in-plane biaxial stretching in directions 1 and 2, the Green strain in these directions can be written…
