| Research Abstract |
Basic experiments were conducted to make clear a possibility of brittle fracture prevention by reinforcement on steel surface. Laser peening was performed as reinforcement method in this study. As a result, it was clarifythat reinforcement on steel surface by laser peening can make deformation capacity until brittle fracture larger under stated conditions for steel, specimen shape and parameter used in thisstudy.
