Study of Viscoelastic Problems Utilizing Commercial Software’s
Objective of the present paper is to present the results obtained utilizing visco-elastic analysis with commercially available software such as FEASTSMT and MARC. FEASTSMT is a structural analysis software being developed at VSSC and marketed. Viscoelastic analysis capability is being regularly used in rocket industry for structural integrity analysis of solid propellant rocket motors. The finite elements required for such analysis are plane-strain, axi-symmetric and three dimensional solid elements. In this paper plane strain configuration is considered for the study with pressure, gravity and thermal loading. Results obtained with the two software are compared in terms of displacement and number of time steps required for the convergence of the exact solution where ever possible. From the study it is found that there are some mismatches in different softwares, in final answers and also the way in which it converges to the solution. The variation of results are presented in the paper.
