Nov 29, 1999 In using this test procedure, you are assuming concrete has a significant plastic strain range. It does not. In compression, it truly acts as an elastic material, but you are likely to get multi-axial stress increases that will fail the sample prior to the onset of localized crushing, usually in a shear or shear-tension mode.Get Price
