the effects of impact energy on the front surface dent depth, back surface resin crack length, damage area and residual compressive strength were studied.
讨论了表面凹坑深度、背面基体裂纹长度、损伤面积以及剩余压缩强度与沖击能量的关系。
it was found that the damage area got by ultrasonic c-scan method will increase with the thickness increase, but the residual compressive strength will not be influenced obviously.
实验结果表明,厚度增加会使层合板内部的超声波c扫描损伤面积增加,但并不会明显影响其剩余压缩强度。
test of concrete under high temperature and the study of residual compressive strength after high temperature;
本论文研究了补偿收缩混凝土高温性能特征,包括残余抗压强度和氯离子渗透性能。
