Mechanism-based multi-surface plasticity model for ideal truss lattice materials
International Journal of Solids and Structures, 2005Abstract The mechanical behavior of ideal truss lattice materials is controlled by the so-called direct action mechanism at the microscale which involves the uniform stretching and compressing of individual truss members. Standard homogenization techniques have been employed to develop a general micromechanics-based finite-strain constitutive model ...

This study examines the performance of four constitutive models according to capacity in predicting metal fatigue life under proportional and non-proportional loading conditions. These cyclic plasticity models are the multi-surface models of Mroz and Garud, and the non-linear kinematic hardening models of Armstrong-Frederick and Chaboche.

In this paper, a three-dimensional anisotropic multi-surface model for the in-plane elastoplastic deformation of paper and paperboard is developed. The model is based on the concept of structural tensors. It employs three different yield functions and parameterised consistency conditions for three different loading scenarios. The evolution of the yield

ABSTRACT Concrete crack measurements are central to earthquake damage assessment procedures, yet few analysis models are equipped to handle crack data as direct inputs. To address this need, this work develops a non‐associative, multi‐surface plasticity model that describes the configuration‐dependent response of a reinforced‐concrete
