The reason is that both temperature and stress combine to affect the accumulation of inelasticstrain.
而在低温保温阶段,应力虽然较高,但温度较低,非弹性应变也不明显。

The modulus of the material decreases and the inelasticstrain increases with the increase of tension stress, and the composite exhibits a largely non-linear stress-strain behavior up to rupture.
