摘要

本文研究了S650高强度钢材料的性能，包括冷成形角的影响。研究了不同冷弯角度(90°、100°、120°、140°、160°和180°)和不同厚度(4 mm和6 mm)的钢板试件。根据拉伸片试验结果，确定了冷弯角与材料屈服应力和拉应力的关系。将考虑冷弯角影响的屈服应力和拉应力与不考虑冷弯角影响的屈服应力和拉应力进行了比较。分析表明，屈服应力和拉应力随冷弯角的增大而减小。利用有限元分析软件ABAQUS中的韧性损伤材料模型进行拉伸试验模拟。实验结果与数值结果吻合较好。收稿日期:2019年3月19日2019年4月20日2019年5月05日

INFLUENCE OF COLD-FORMED ANGLE ON HIGH STRENGTH STEEL MATERIAL PROPERTIES

This paper describes a study of the S650 high strength steel material properties including the effect of cold -formed angle. Coupon specimens with different cold-formed angles (90°, 100°, 120°, 140°, 160° and 180°) and different thicknesses (4 mm and 6 mm) were examined. Relationships between cold-formed angle and yield stress as well as tensile stress of the material were determined, based on the tensile coupon test results. Yield and tensile stresses assessed by consid ering the influence of the cold-formed angles were compared with those without considering this influence. Analyses revealed that both yield and tensile stresses decreased with increasing cold-formed angle. Ductile-damage material models available in the finite element analysis software ABAQUS were used to simulate tensile coupon tests. The experimental and numerical results showed good agreements.
