WebSo point A is called proportional limit point, is the point above any applied stress doesn't obey linear stress-strain behavior (Hooke's Law). And the elastic limit or yield point is the point where a combination of elastic and plastic behavior is still there (although it's not in the plastic region) so according to ASKLAND BOOK at that point the departure of the plastic … WebThe material has now moved into the region referred to as plastic deformation. In practice, it is difficult to identify the exact point at which a material moves from the elastic region to the plastic region. As shown in the figure below, a parallel line offset by 0.002 strain is drawn. Where that line intercepts the stress-strain curve is ... graphic designer education requiredWebThe area under the stress-strain graph is the strain energy per unit volume (joules per metre3).
