本文采用电阻应变片测量裂纹尖端区域应力分布的方法,确定复合材料的断裂韧性。文中采用K标定法对斜拉玻璃钢GRP桥用复合材料的断裂韧性进行了试验与分析。
In this paper, the method of measuring the stress distribution in crack tip region by using resistance strain gauges is used to determine the fracture toughness of the composite material. In this paper, the fracture toughness of composites for GRP bridges with glass fiber reinforced plastics is experimentally tested and analyzed using K calibration method.
