The mopohology of slip bands for materials with two different slip modes: pure Cu and Cu-Zn alloy after prestraining and cyclic softening has been observed.

Ｃｕ－Ｚｎ合金循环软化后有两种衬度的滑移带，而纯Ｃｕ则主要表现为驻留滑移带，说明两种材料疲劳应变的容纳方式不同。

On the basis of full consideration of the slip band appearing and the shape fixability of forming parts,reasonable conditions in stretch forming of airplane mirror skins have been determined by means of analysis of the effects of stretching velocity, geometrical dimensions of blank, geometrical parameters of dies and lubrication methods on forming quality.

在充分考虑滑移带出现与成形件贴模度的基础上，通过分析拉形速度、毛料几何尺寸、模具几何参数、润滑方式对成形质量的影响，确定了合理的飞机镜面蒙皮拉形条件。

A simultaneous set of singular integral equations are derived for the case where there are a crack and two pairs of symmetrical slip bands.
