SOME ASPECTS OF THE NONLINEAR FINITE-ELEMENT METHOD

The paper discusses four separate aspects of the non-linear finite ele ment method: (i) An alternative formulation for the static co-rotation al technique in conjunction with a simple faceted shell idealisation. (ii) Solution procedures for non-linear dynamics with emphasis on ener gy conserving techniques (iii) The use of interface elements and fract ure energy related softening ''stress-strain'' curves for modelling mi xed mode delamination in ''composites'' (iv) Hybrid static/dynamic sol ution procedures. While the topics are separate, there are links and t hese are explored. (C) 1997 Elsevier Science B.V.
