A General Time Dependent Constitutive Model: Part II— Application to a Titanium Alloy1

Abstract

Given the mathematical framework and specific viscoelastic model in Part I our primary goal in this second part is focused on model characterization and assessment for the specific titanium alloy, TIMETAL 21S. The model is motivated by experimental evidence suggesting the presence of significant rate/time effects in the so-called quasilinear, reversible, material response range. An explanation of the various experiments performed and their corresponding results are also included. Finally, model correlations and predictions are presented for a wide temperature range.
