Plasticity, Pineridge Press.
- Subroutines and driver programs for non-linear
elastic, elasto-plastic and elasto-viscoplastic problems, both static
- The Fortran source code is also available on
diskette from the publisher (£500).
- In one dimension the following problem types can be
(a) non-linear quasi-harmonic problems (solution either by
direct iteration or by Newton-Raphson iteration);
(b) non-linear elastic, elasto-plastic and elasto-viscoplastic problems;
(c) non-layered or layered elasto-plastic analysis of Timoshenko
In two dimensions the static problem types are
(a) elasto-plastic and elasto-viscoplastic analysis of plane and
(b) non-layered/layered elasto-plastic analysis of Mindlin plates.
The two dimensional dynamic problem types involve
two-dimensional plane stress/strain and axi-symmetric non-linear
dynamic transient analysis
(a) DYNPAK small/large elastic deformation or small elasto-viscoplastic
deformation with explicit central-difference time integration;
(b) MIXDYN small/large
deformation elastic or small deformation elastic-plastic (Tresca, Von
Mises, Drucker-Prager, Mohr-Coulomb) and a choice of time integration
algorithm (explicit, implicit, combined implicit-explicit). Flow
diagrams and solution algorithms are included in the text.
