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(duì)以上問(wèn)題,首先以單層板理論為基礎(chǔ),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(qiáng)度和壽命預(yù)測(cè)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(duì)材料t300 / bmp - 316單向?qū)雍习蹇v向、橫向及面內(nèi)剪切靜載力學(xué)性能及疲勞特性進(jìn)行了試驗(yàn)研究,并采用最小二乘法擬合得到各主方向正則化疲勞壽命表達(dá)式,以及單層板各主方向疲勞加載剩余剛度退化表達(dá)式及剩余強(qiáng)度退化表達(dá)式;試驗(yàn)同時(shí)驗(yàn)證了單向?qū)雍习? - 2面上明顯的剪切應(yīng)力應(yīng)變非線性關(guān)系。
