摘要
试验研究了具有一定形貌及粗糙度的激光毛面薄钢板及同材质普通薄钢板的失稳行为。结果表明激光毛面薄钢板变形局部化过程明显滞后于普通板，其表层弥散分布的预应变硬化点在稳定薄板变形、延缓变形局部化过程中起到重要作用。
The plastic instability behavior of the laser-textured steel sheet with defined surface features is investigated. Comparison is made with the normal sheet taken from the same coil of meatal sheet. It is found that,the laser-textured sheet has the tendency to postpone strain localization;the dispersed prestrain hardening on the surface of laser-textured sheet plays an important role in stabilizing deformation and delaying the process of strain localization.
