Constitutive description of yield properties for heterogeneous polymers
Abstract
In this contribution, an approach is proposed to determine the homogenized properties for heterogeneous RVEs at the micro-scale so that the obtained homogenized properties can be used at the macro-scale and consequently, time consuming coupled multi-scale analysis could be avoided. A developed constitutive model, based on single model compressible Leonov model, to account for elasto-viscoplastic behavior of polymers is used. An effort is given to determine the yield properties for heterogeneous polymeric based material. A mathematical relation is proposed which relates the yield stress of the material and different yield properties (Eyring properties for the model used in this study). Then, coupled multi-scale analyses are performed using an arbitrary RVE and the yield stresses are taken form the deformation behavior curves. According to the yield stresses of coupled analyses, the homogenized properties that could be used for the specific RVE are determined. © 2014, Advanced Engineering Solutions (AES.COM) Ottawa, Canada.
