Non-Linear Behaviour

general - any form of structural analysis where solution progress depends on the load sequence as well as the initial conditions.

material non-linear, general - solutions involving non-linearities in material properties.

creep - the material behaviour at high temperatures when, at constant stress, the strain increases with time. Similarly, at constant strain, the stress decreases with time. This is called relaxation .

plasticity - this is time-independent material phenomenon when permanent plastic strains build up due to stresses exceeding the yield stress.

Benchmarks P06 , R0026 , R0030 , R0049 .

visco-elasticity - non-linear material behaviour in which the effects of plasticity and creep are both exhibited, so that the stress is dependent on the strain rate.

Texts HT19 , HT21 , HT30 , R0018 , R0080 , R0085 .

geometric non-linearity - occurs when the changes in the deformed geometry of a loaded structure need to be taken into account during the solution process. Small or large deformations and/or strains may be involved.

contact analysis - the study of surfaces which can, under loading, come into contact with or separate from one another.

explicit solution scheme - an algorithm, used in many time or load dependent analyses, whereby the solution for the next increment of time or load is obtained entirely from the solution and conditions at the previous step. It is used in both static and dynamic analyses.

Texts FEP , HT19 , R0018 , R0080 , R0085 , R0095 .

geotechnical analysis - the structural analysis of earth-like natural materials incorporating such special effects as pore fluids.
