Firstly,a 2-D pure shear microbuckling model is proposed. With further considering the different normal bending strains of a laminate in different layers,which will lead to a tension/shear mixed deforming mode,a 2-D tension/shear microbuckling model is proposed afterwards.
首先,建立了一个二维纯剪切的微屈曲模型;在此基础上,考虑层合板弯曲过程中不同层名义应变不同,导致其屈曲实际是一拉/剪混合模式,又建立了一个二维拉/剪混合微屈曲模型,并对其临界屈曲参数和后屈曲过程进行了分析。
