摘　　要：对MTS810.23试验机开展单试样法测定J积分的应用研究,对J积分快速试验应用到生产检验提供了条件。试验表明,对于能够保证裂纹缓慢稳定扩展,弹塑性比较好的材料才更适于用J积分试验来获取材料的断裂韧度参数。JIC is determined by using single specimen method on MTS810.23 testing system.It offers the condition for faster JIG testing in production. The testing shows the material which can ensure the crack to grow slowly and the elasticity is better may obtain preciser parameters of fracture toughness by the JIC testing.
