    The macroscopic material behavior of concrete is influenced by the geometry, spatial distribution and material properties of individual material constituents and their mutual interactions. Therefore, it is essential to study the influence of each material constituent in order to estimate the residual strength of the structural components. Thus, failure of concrete is a complex phenomenon due to its multiscale and multiphase nature. When the normal stress in a material reaches its tensile strength

    of test for the measurement of damping. In addition, the notation of complex modulus describes conventionally for damping and dynamic stiffness of linear viscoelastic materials, where the methods of vibration test are considered for measurement of complex moduli of composites. With the help of this test of plates and beams to find dynamic elastic moduli also get evaluated. In vibration test, notation for complex modulus is suitable for portrayal of dynamic behavior of linear viscoelastic composites

    ballast density, Eb is modulus of elasticity of the rail ballast in N/m2,Bs, Ls, are width and length of the rail sleeper and Hb is the high of the rail ballast as shown in Figure 2.1.1. Furthermore, Ahlbeck et al. (as cited in Sun & Dhanasekar 2002)[4] determine the values of sub-ballast mass Msb, stiffness Ksb and subgrade stiffness Ksg as: where θsb is internal friction angle of the sub-ballast (35o as suggested by Ahlbeck et al.), ρsb is the sub-ballast density, Esb is modulus of elasticity of the

    include the amount of aggregates and the ratio of water to cement. This experiment was therefore aimed at determining the ultimate compressive strength of different concrete samples after 14 days. Additionally, other properties of the concrete such as modulus of elasticity and Poisson ratio were also determined. Engineering Team Members 1. 2. Procedure for the Experiment The procedure of the experiment consisted of two main parts. However, before the experiment was started, the concrete cylinders which

    Aluminium’s Elastic Modulus was 48.3GPa whereas the accepted literature value for polycrystalline aluminium is 69GPa. b) Possible reasons for the difference between our value and the literature value could be the fact that the machine we used would have absorbed some of the load, the dials and other measuring tools were difficult to get a very accurate reading from and how the experiment was set up on our behalf. c) Single crystal specimens of a material will have a lower elastic modulus than a polycrystalline

    Case Study of “Does America really need manufacturing”. Sriharsha Vennelaganti-Fs0792 1. Summary: In the case study we can see that the authors talk about the importance of innovation when it comes to the long-term success of every product company. By reading the article one gets an understanding that the authors are asking executives of any product company should not view manufacturing as a cost center and by shifting their manufacturing units offshore they are hindering a company’s capacity
