The effects of element partitioning method and temperature model on the precision of one dimensional finite element analyses of transformation and thermal stress were investigated.
Partitioning using Gauss integration scheme is found to be effective only in pure thermal stress analysis but not so effective in analysis considering stress induced by transformation and permanent strain. To treat precisely the mechanical property of materials under transformation, each phase generated at each time increment is analyzed part by part individually.
The behavior of the phase transformation plastisity is successfully predicted in terms of the plane stress constitutive equation for flat plate.
