In these cases the stress is no longer proportional to the strain.Non-linear problems are inherently more complex to analyse than linear problems. And the principle of superposition (which states that the resultant deflection, stress, strain in a system due to several forces is the algebraic sum...

This monograph describes the numerical analysis of non-linearities in structural mechanics, i.e. large rotations, large strain (geometric non-linearities), non-linear material behaviour, in particular elasto-plasticity as well as time-dependent behaviour, and contact. Based on that, the book treats...

In this work a 3D geometrically non-linear micropolar finite element formulation based on Biot-like tensor representation of stresses, couple stresses, strains and curvature is presented. The discrete approximation is based on hexahedral finite elements with Lagrange interpolation for displacements and ...
The non-linear analysis of reinforced concrete structures using finite element techniques is presented. Tensile cracking, the multiaxial compressive response of concrete and the yielding of steel reinforcement are the main non-linear effects studied. Several models of multiaxial material behaviour, b...
