关于松弛应变-残余应力关系式,即[1]中(11)式,由于其中之释放系数 B′不是常数,它不仅与几何-弹性参数有关,而且夹进了未知的应力状态参数(?),这必然会给以后残余应力以求解带来困难.事实上文献[2]已成功地把未知应力参数σ_1、σ_2、(?)与几何-弹性常数彻底地分开,即把松弛应变表为 Regarding the relaxation strain-residual stress relation, ie, the formula (11) in [1], because the release coefficient B′ is not a constant, it is related not only to the geometric-elastic parameters but also to the unknown stress state parameters (?) This will inevitably bring difficulties to the solution of residual stresses in the future. In fact, the literature [2] has successfully completely separated the unknown stress parameters σ_1, σ_2, (?) from the geometric-elastic constants, that is, the relaxation strain is expressed as
