WebThe two-surface plasticity theory introduces the concept of the “bounding surface” to describe a slowly evolving bounding regime in stress space that defines the limiting value of the plastic modulus during the course of monotonic or cyclic plastic loading. From: Cyclic Plasticity of Metals, 2024 About this page WebThe mathematical foundation of the general bounding surface constitutive formulation in plasticity is presented. Along these lines the concept of hypoplasticity is formally introduced, and it is shown that a particular class of hypoplastic formulations arises …
