Buckling of cracked members under tension

Abstract

The buckling characteristics of cracked elastic plates subjected to uniaxial tensile loads are analysed by aid of a finite element method based upon linear bifurcation theory. The dependence on geometry and boundary conditions of some features of pre-buckling stress states and critical loads and modes are discussed in relation to previous findings for centrally cracked plates. The effect of biaxial loading is considered for one specific geometry. Buckling of three types of edge cracked members is investigated and discussed in particular regarding attainable stress intensity factors at fracture mechanics testing. Statements are made about the interaction of local buckling and fracture. Some phenomena warranting further theoretical consideration are observed. © 1980.
