摘要
测试了在不同加载速率下,典型建筑用钢焊接接头的断裂韧性值。在准确把握材料在地震载荷下本构关系的基础上,通过局部法,实现了由静载断裂韧度值对地震载荷下接头断裂行为的成功预测。表明局部法可有效地评定接头在高加载速率下的断裂行为。
The fracture toughness for welded joint is measured at different loading rates corresponding the earthquake loading,the fracture behavior on earthquake loading is predicted successfully from static fracture toughness result based on the local approach.The temperature improving in the material itself is considered during the prediction analysis.It is proved that the local approach is effective to analysis the fracture behavior on dynamic loading.
