采用层间结合的弹性层模型,讨论层间结合状态对ELS和ENF试样柔度与层间裂纹扩展力计算值G_1的影响。计算表明,对于非完好的层间结合,层间裂纹长度趋零,能量释放率保持有限值;不同的层间结合状态参数,G_1计算值有极大的差异。因此,在G_(1)的这种测试中,应该将层间结合的影响纳入考虑。
Modelling coculation state between layers by means of a elastic layer, authers approach compliance and G 1 of delamination in ELS and ENF of composite. It is shown in present paper that the energy release rate remainslin finite value when the crack length vanishes and value of G1 is varable in large range for different values of leyer copulation state parameters. Therefore, the influence of copulation state between layers on G1 would be taken into consideration in measureme of G1. in ELS and ENF of composite
