The temperature and strain rate dependent (TSRD) tensile strength of polymer closely concerns the service safety in wide temperature range and dynamic load. In this study, based on the decoupled modeling method, a theoretical model of TSRD tensile strength of amorphous polymer was established. The model quantifies the relationship between the TSRD tensile strength, Young's modulus, heat capacity, glass transition temperature and melting temperature of amorphous polymer. The model predictions demonstrated an excellent consistency with the experimental data. Furthermore, the influencing factors analysis regarding the TSRD tensile strength were conducted. This study contributes a theoretical method to conveniently predict the TSRD tensile strength of amorphous polymer, and would be helpful to the evaluation and application of polymer in extreme conditions.

The use of composite materials in several sectors, such as aeronautics and automotive, has been gaining distinction in recent years. However, due to their high costs, as well as unique characteristics, consequences of their heterogeneity, they present challenging gaps to be studied. As a result, the finite element method has been used as a way to analyze composite materials subjected to the most distinctive situations. Therefore, this work aims to approach the modeling of composite materials, focusing on material properties, failure criteria, types of elements and main application sectors. From the modeling point of view, different levels of modeling—micro, meso and macro, are presented. Regarding properties, different mechanical characteristics, theories and constitutive relationships involved to model these materials are presented. The text also discusses the types of elements most commonly used to simulate composites, which are solids, peel, plate and cohesive, as well as the various failure criteria developed and used for the simulation of these materials. In addition, the present article lists the main industrial sectors in which composite material simulation is used, and their gains from it, including aeronautics, aerospace, automotive, naval, energy, civil, sports, manufacturing and even electronics.

“…the tensile strength, which belongs to the crucial mechanical property's indicators, is strongly affected by temperature and the damage condition of materials. [2,4,[8][9][10] Consequently, it is imperative to study the tensile strength of fiber/polymer composites at different temperatures and damage degree. In particular, reasonably characterizing the quantitative effect of temperature and damage on the tensile strength of fiber/polymer composites becomes fundamental and attracts widespread interest.…”

With the rapid development of aerospace technology, the application of fiber/ polymer composites in extreme environments especially at high temperature gets more and more extensive, the tensile properties of fiber/polymer composites in different temperatures environment have become a critical issue of concern. In this work, a temperature and damage dependent tensile strength (TDDTS) model for fiber/polymer composites was presented based on the force-heat equivalence energy density principle and the damage failure analysis. The TDDTS model considers the combined effects of temperature, the evolution of constituents' properties and damage with temperature. Meanwhile, the TDDTS model has advantages from the aspects of prediction accuracy and convenience by comparison with our previous model and the Curtin's model.Further on, the influencing factors analysis of fiber/polymer composites concerning the tensile properties and damage evolution with temperature was conducted. This study offers a reliable model for predicting the TDDTS of fiber/polymer composites, and provides important insight for the strength degradation mechanism and the damage evolution.
