Залучення теорії гнучких пластин та оболонок до аналізу пружної деформації на першій стадії вирубування деталей прямокутної форми
In the paper there is an attempt to use theory of flexible plates and shells to explain the behavior of the thin stripes under blanking and punching operations. Now an opinion exists that results of thick sheet blanked parts of usually round shape are applied to thin sheet ones including also intricate shapes. But judging on the wear of punches and dies, the picture of their loading is changing at the end of the first stage of blanking - the flexible deformation. Attempts to explain this process for thin sheet material are connected with redistribution of acting loads because of flexibility of sheet stock.
