The elastic modulus is calculated by E i = (σ i-σ i-1) / (ε i-ε i-1) in each step of the stress-strain diagram. This material model enables definition of asymmetric stress‑strain diagrams. The material model is suitable for (unreinforced) masonry walls with loads in the plane of the pane. The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows material softening, which can be different in the local x- and y-directions of a surface. It is possible to specify the limit tension stresses σ x,limit and σ y,limit as well as the hardening factor C H. This material model allows the definition of material properties (modulus of elasticity, shear modulus, Poisson's ratio) and ultimate strengths (tension, compression, shear) in two or three axes. Note that you need a licence for add-on RF-COM for this component to work. Orthotropic Plastic 2D/3D (Tsai-Wu 2D/3D) Language Multilingual Latest Release May 1.
