Metal forming problems generally involve large plastic deformations. in cold forming most materials have a nonlinear strain hardening behaviour. F.E.M. solutions of. such problems require elastic plastic analysis and an incremental approach. While a number of such approaches exist they require fairly small step size and hence a large computational effort Madnaik, Maiti and Chaturvedi (1) had proposed a modification to the tangent modulus method of Yamada et al(2) and showed that this method is able to solve the problem of plane strain compression with considerably less computational effort and reasonable accuracy; and presented results to show the stress distributions at various levels of reductions and for different aspect ratios(3) This paper uses the same procedure termed the Modified Elastic Plastic Incremental Analysis Procedure (MEPIAP) for obtaining solution to another problem i.e. Plane Strain Compression of Preshaped Material between Inclined Tools. |
