Young s Modulus and Poisson s ratio

a) rubber because it has high young\'s modulus so for high values of stress its deformation will be less. b) concrete as its poisson\'s ratio is least so it will avoid linear contraction or reduction in size of its transverse area.

                              1)Grid dependency test means refining the mesh or grid and checking the results and how much it differs from the previous. Basically we refine the mesh that is reduce the element size and see how do the results change. So as we refine the mesh we get more accurate value untill the change in mesh size stops affecting the…

                                    It depends on the material we are using like for metals both the strengths are almost equal but for materials like concrete the compressive strength is way more than its tensile strength. So both require the same capacity of the machine
