Elastic-Plastic Constitutive Equation Using Non-Orthogonal Curvilinear Coordinates and its Application in Numerical Methods

Conference paper


The elastic-plastic constitutive equations in solid mechanics are derived using arbitrary non-orthogonal curvilinear coordinates. These general equations, obtained in this paper, are applicable in both finite element and finite difference methods for dealing with irregular domains. Some examples are illustrated.
