文獻[ 15 ] [ 16 ]討論了非自治單種群捕獲模型,在周期解存在唯一及全局漸近穩定前提下,為獲得最大可持續捕獲量,而得到最優捕獲策略 -
In the model, johnson - cook strength is combined with gurson - tvergaard - needleman yield criteria, and random distribution of microvoids is used. results show that quasi - periodic axial fracture will appear, which obstructs the mirror current of the armature
在給定微孔洞的初始擾動時,計算結果解釋了鋁電樞表面將要形成的不穩定性,它導致了電樞外表面出現周期性的軸向裂紋,阻礙了鏡像電流,使fcg損耗增加。
