Slow crack growth (SCG) is a time-dependent quasi-brittle type of failure that polyethylene (PE) materials exhibit under low stress levels. The interplay between the crack and its plastic zone dictates complex damage behavior of continuous and discon

This study aims to develop a general model to examine the weathering-induced degradation of a polycarbonate/acrylonitrile–butadiene–styrene (PC/ABS) blend under various temperatures and UV irradiance levels. The carbonyl index (CI) was measured w

Surface flaws in structural materials are most likely to be generated during service time. One of the most general shapes of surface flaws is the semi-elliptical surface crack. Frequently, the slow crack growth (SCG) of a crack has been fitted based

Weathering-induced degradation causes a premature failure of polymeric materials in outdoor applications. In this study, the polypropylene and talc composites were degraded by accelerated and outdoor weathering. By comparing the degradation degree th

In this study, thermotropic liquid crystal polymer (LCP)-based hybrid materials with various carbon fiber (CF) and polyphenylene sulfide (PPS) contents were developed to replace the heavy metal brackets used for liquid crystal displays (LCDs) in thin

The crack layer (CL) model can be used to theoretically simulate unique discontinuous slow crack growth (SCG) and the consequent lifetime of pipe-grade high-density polyethylene (HDPE). However, its application has been limited to several specimen co

The major failure aspect of high-density polyethylene pipes under the service condition is the discontinuous slow crack growth (DSCG) from the initial defects inside the pipe wall. In this study, the DSCG kinetics for an internal eccentric crack is t

The crack layer theory, proposed by A. Chudnovsky many years ago, can be a very effective tool to quantitatively model slow crack growth in engineering thermoplastics. However, the large number of input parameters required by this theory has been a t
