A Phenomenological Constitutive Model Constructed for PC/ABS Blends

Abstract

Based on previous available constitutive models, a phenomenological constitutive model has been constructed and is proposed to describe the strain, strain rate and temperature dependentdeformation behavior of PC/ABS blends. In this paper, four quasi-static uniaxial tension tests of a specimen tested at different strain rates and temperatures were used to identify the constitutive model constants. By using the proposed constitutive model, predicting the stress-strain behavior of the PC/ABS blend tested at certain strain rate and different temperatures compares well to the behavior exhibited from the tests. From comparison between the DSGZ and the proposed models, proposed model shows a better prediction. Evaluation of the proposed constitutive model was also presented and it has revealed that the proposed model might have a potential to be used for predicting a wide range of temperatures and high strain rates behavior of PC/ABS blends.

Viscoelasticity and viscoplasticity of polypropylene/polyethylene blends

“…Constitutive models for the analysis of plastic deformations, damage and cavitation of polymers toughened with rubber particles were proposed by Steenbrink and van der Giessen (1997), Chen and Mai (1999), Liang and Li (2000), Kuroda et al (2004), and Mae et al (2008). Thermo-viscoelasticity of polymer blends was recently modeled by Machmud et al (2006) and Shaoqiu et al (2007). The viscoelasto-plastic behavior of a polymer blend reinforced with nanoclay was analyzed by Drozdov and Christiansen (2007) for a fixed composition of the matrix.…”

Deformation response and constitutive modeling of PC, ABS and PC/ABS alloys under impact tensile loading

“…Based on the previous phenomenological models and the experimental results of polymers at temperatures 253 K and 323 K and strain rates 1 × 10 −3 and 5 × 10 −3 , Duan et al [22] developed a much more complex model. But this model [22] cannot describe the deformation behavior of PC and ABS resin at high temperature and high strain rate [23]. Based on the previous models [19][20][21][22], Yin and Wang [10] develop a phenomenological constitutive model to describe the deformation behavior of PC/ABS alloys at elevated temperatures and high strain rates under impact compressive loading.…”

Advancing the Characterization of Recycled Polyolefin Blends with a Combined Experimental and Numerical Approach to Thermomechanical Behavior

“…This material model was also applied to study the crack tip plasticity in polymer/rubber blends [ 20 ]. Alternatively, a phenomenological constitutive model has been constructed for predicting a wide range of temperatures and high-strain-rate behaviors of PC/ABS blends [ 21 ]. Based on a DSGZ model, a modified phenomenological constitutive model was proposed to account for the loading and unloading [ 22 ].…”
