Abstract Scope |
With every industry striving to reduce the weight of components and structures from aerospace and automotive to wind and solar power, structural materials with anisotropic and asymmetric behavior are becoming more popular. Since an accurate and efficient description of the elastic limit is necessary to describe both the deformation during manufacturing and the final component strength, we propose a new yield criterion for pressure-insensitive anisotropic and anisotropically asymmetric solids. Previous orthotropic yield criteria were extended using a fully implicit description for the anisotropy in both the strengths and strength differential effects (asymmetry). This provides for the modeling of asymmetry in shear for orthotropic materials and applications to lower symmetry materials such as triclinic. This presentation will explore the world of implicit and explicit models of anisotropic and asymmetric yielding, introduce our proposed yield criterion, and provide experimental case studies for various applications. |
