Abstract
A simple modification of J2‐flow theory is made which enables it to approximately represent the reduced stiffness and increased plastic flow of corner‐theory response to non‐proportional loading. The key idea involves making the plastic modulus a function of the loading direction. A concise radial‐return type numerical algorithm is presented for the constitutive integration.
