金属材料的拉力试验,是工厂理化试验室日常试验工作中最多的一项试验。这是因为这种试验中所获得的结果,在许多场合已经足够正确的用来判断材料其他各种变形(如弯曲、扭转、压力、剪切时的性能)作为设计之依据;另一方面是因为这种试验较之一般试验简单易做。 拉力试验,除了一般 Tensile testing of metallic materials is the largest test of daily physical and chemical testing in a laboratory. This is because the results obtained in this kind of test have, on many occasions, been sufficiently accurate to be used as a basis for the design in judging various other deformations of the material (such as bending, twisting, pressure and shearing) and on the other hand Because this test is simple and easy to do than the average test. Rally test, except in general
