WebGenerally, nobody is perfectly elastic and perfectly plastic; but they are between these two extremes. Normally, quartz is the perfectly elastic body and putty, the wax is perfectly plastic bodies. Rigid bodies: Bodies which do not get deformed or have very small deformation on applying external force are called rigid bodies. Webthe case of a rigid sphere indenting a frictionless perfectly plastic half-space (i.e. no hardening). The results show that the ratio between the average contact pressure and the yield strength decreases as the depth of indentation is increased. Note that the slip-line analysis does not

WebQuestion: (30 points) Consider dynamic (rapid) indentation of a rigid-perfectly plastic material by a sharp rigid cone of apex angle 90 degrees. The hardness value obtained from such a test is called the dynamic hardness of the material. The dynamic indentation can be modeled as a process in which the full indentation load is applied instantaneously. WebThe modeling of materials as rigid-perfectly-plastic facilitates analysis of many problems due to the fact that bodies made from such materials satisfy two extremal principles. In turn, these extremal principles can be used to find upper and lower bounds to the limit load associated with a given boundary-value problem.
