1. Constitutive modelling of hydrolytic degradation and viscoplasticity in glassy polymers: An effective temperature approach.
1. 玻璃态聚合物中水解降解与粘塑性的本构建模：一种有效温度方法PMID:日期:2026-06Hydrolysis is the primary degradation mechanism in biodegradable polymers in aqueous environments, involving water diffusion and polymer chain scission. These two processes dynamically alter the composition of the polymer, significantly influencing its thermomechanical properties and deformation behaviour. In this work, we develop a constitutive modelling approach that couples water diffusion, hydrolytic chain scission and viscoplastic deformation in glassy polymers. The effect of water concentration and hydrolytic degradation on the mechanical properties is captured through an effective temperature, reflecting the reduction in glass transition temperature brought about by water uptake and the reduction in average molecular weight. The model is calibrated using experimental data for polylactic acid (PLA), including thermo-mechanical characterisation in the wet degraded state and dry undegraded state at different temperatures. Our model accurately captures the evolution of molecular weight and water concentration distributions measured experimentally, and successfully predicts the deformation behaviour at different degradation stages. The potential of the model for weakly coupled simulations is also illustrated in representative case studies. Overall, this study supports the use of the effective temperature as a practical yet physically-motivated method for capturing the effect of degradation on mechanical properties, while providing a robust tool for the design and analysis of degradable polymer devices.

2. Quasi-static and dynamic response, and texture evolution of two overaged Al 7056 alloy plates in T761 and T721 tempers: Experiments and modeling.
2. 两种过时效态Al 7056合金板材在T761和T721回火状态下的准静态和动态响应及织构演变：实验与建模PMID:日期:2020-07The thermo-mechanical behavior and texture evolution of two overaged Al 7056 alloy plates, in T761 and T721 tempers, are measured over a wide range of strain rates (10 - 3 × 10 s) and temperatures (22-300 °C) under uniaxial tension and compression along the thickness direction, i.e. normal to the plate surface. A detailed study of the initial microstructure reveals an increase in precipitate size and decrease in density of precipitates, as the alloy is aged from the T761 to T721 temper; which in turn affects the flow stress and strain hardening behavior. Differences in flow strength and strain hardening rate, as well as tension-compression asymmetry in the two tempers, are apparent at the lower temperatures (22 °C & 100 °C) and decrease significantly at the higher temperatures (200 °C & 300 °C). Furthermore, initial texture measurements show a strong texture gradient along the normal direction (ND) of the plate. This texture gradient affects the ultimate stress insignificantly. However, it does have a considerable effect on the failure strains of specimens taken from different locations through the thickness. A transition from shear fracture at and below 200 °C to cup and cone fracture mode above 200 °C is observed in tension. Both tempers exhibit a positive strain rate sensitivity (SRS) that is dependent on temperature and strain rate. A sharp decrease in flow stress is found at 300 °C. The Khan-Liu (KL) model is modified to correlate with the measured thermo-mechanical responses of the two tempers over the studied, wide range of strain rates and temperatures. There is a close correlation between simulated and observed results.

3. Thermally-activated constitutive model including dislocation interactions, aging and recovery for strain path dependence of solid solution strengthened alloys: Application to AA5754-O.
3. 包含位错相互作用、时效回复的热激活本构模型及其在固溶强化合金应变路径依赖性中的应用：以AA5754-O铝合金为例PMID:日期:2015A thermally-activated constitutive model is developed based on dislocation interactions, crystallographic orientations and microstructural evolution to describe the elasto-plastic stress-strain behavior during multi-axial loading. The aim is to contribute to the quantification of complex strain path response in solid solution strengthened alloys. In detail, dislocation/dislocation interactions are incorporated in the model to quantify latent and kinematic hardening phenomena during loading path changes. Dislocation density-based constitutive relations are included to account for dislocation features such as dislocation forests, walls and channels. Moreover specifically, dislocation/solute atom interactions are also considered in order to account for both dynamic and static strain aging as well as static recovery. The model is validated against multiple multi-axial data sets for AA5754-O with changes of loading path and various degrees of pre-strain and time intervals between tests.
