A progressive damage method of predicting the static strength and the fatigue life of mechanically fastened joints in fibre - reinforced plastics is established in the paper, which is based on the theory of unidirectional ply
本文針對以上問題，首先以單層板理論為基礎，建立了層合板接頭靜拉伸及疲勞載荷作用下三維逐漸損傷分析的強度和壽命預測方法。 -
An experimental program which includes lots of unidirectional laminae is conducted using t300 / bmp - 316 material for researching the static and fatigue behaviour of the unidirectional ply. the experimental research for mechanical behaviour of a unidirectional lamina is to set up expressions of the normalized fatigue life, the residual strength degradation and the residual stiffness degradation of a unidirectional ply in the longitudinal, transverse and in - plane - shear directions, which also verifies the fact of nonlinear shear stress - strain behavior of a unidirectional ply in the 1 - 2 planes
其中:分別對材料t300 / bmp - 316單向層合板縱向、橫向及面內剪切靜載力學性能及疲勞特性進行了試驗研究，並採用最小二乘法擬合得到各主方向正則化疲勞壽命表達式，以及單層板各主方向疲勞加載剩餘剛度退化表達式及剩餘強度退化表達式;試驗同時驗證了單向層合板1 - 2面上明顯的剪切應力應變非線性關系。
