Masonry Wall

A masonry wall is exposed to a distributed load in the middle of its upper part. Isotropic Masonry 2D material model is compared with the Isotropic Linear Elastic one with surface stiffness property Without Tension in the nonlinear calculation.

Elastic Bending – Continuous Load

A thin plate is fully fixed on the left end and a uniform pressure is applied on the top surface.

Loaded Plastic Beams with Decaying Stress-Strain Curve

Four columns are fixed at the bottom and connected by the rigid block at the top. Block is loaded by the pressure and modeled by an elastic material with high modulus of elasticity. Outer columns are modeled by linear elastic material and inner columns by a stress-strain diagram with the decaying dependence. Assuming only small deformations theory and neglecting structure's self-weight, determine its maximum deflection.

Plastic Bending – Tapered Cantilever

A tapered cantilever is fully fixed on the left end and subjected to a continuous load considering plasticity.

Plastic Bending with Different Plastic Strengths

A cantilever is fully fixed on the left end and subjected to a bending moment on the right end. The material has different plastic strengths in tension and compression.

Plastic Bending with Zero Tensile Strength

A cantilever is fully fixed on the left end and subjected to a transverse force and an axial force on the right end. The tensile strength is zero and the behaviour in the compression remains elastic.

Plastic Bending – Moment Load

A cantilever is fully fixed on the left end and subjected to a bending moment considering plasticity.

Plastic Bending – Continuous Load

A thin plate is fully fixed on the left end and subjected to a uniform pressure considering plasticity.

Comparison of Nonlinear Material Models

One layered square orthotropic plate is fully fixed at its middle point and subjected to the pressure. Compare the deflections of the plate corners for different fiber angles to check the correctness of the transformation.

One-Dimensional Plasticity with Hardening

A three-dimensional block, made of elastic-plastic material with hardening, is fixed on the both ends. The block's middle plane is subjected to the pressure load. The surface of plasticity is described according to the Tsai‑Wu plasticity theory.
