Flow rule in plasticity
WebMay 3, 2024 · If the yield function is used as the plastic potential, then the normality rule is known as the associate flow rule. Otherwise, it is known as the non-associate flow rule … WebJul 11, 2014 · The plastic flow is mainly due to the rate of plastic strain increment vector and material flow at yield is governed by the gradient of the plastic potential flow. It is called associated plasticity, if the angle of dilation is equal to the angle of internal friction. It means that the plastic flow develops along the normal to the yield surface.
