Triaxiality abaqus

Web1. A multiaxial creep-fatigue prediction method based on ABAQUS comprising the steps of: S1: establishing an ABAQUS finite element model, and defining viscoplastic constitutive equation of a material to be tested in process of cycling loads by means of a user subroutine UMAT; S2: determining model parameters required by the viscoplastic constitutive … WebFor steel‒plate concrete composite structures, shear connectors, including studs and tie-bars, are critical in resistance of interfacial shear between steel plate and concrete core. The previous push-out experimental results indicated that the primary factor resulting in significant decreases in ultimate shear capacities of shear connectors under cyclic …
