Abstract: The initial postbuckling behavior of a shallow section of a spherical shell subject to external pressure is studied within the context of Koiter’s general theory of postbuckling behavior. ...

Abstract: Buckling and initial postbuckling behavior is determined for thin, elastic cylindrical shells of elliptical cross section. This study complements the buckling and advanced postbuckling calculations ...

Abstract: Aspects of postbuckling behavior are investigated for structures undergoing plastic deformation. The structures singled out are characterized by a highly imperfection-sensitive behavior where buckling ...

Abstract: Kagome truss plates have properties that suggest they should be uniquely effective as an actuation plane for sandwich plates: a Kagome truss plate has in-plane isotropy, optimal stiffness and ...

Abstract: A theoretical study is made of the implications of a Dugdale-Barenblatt model for fatigue crack growth under steady cyclic loading. Residual plastic stretches and the effects of crack closure ...

Abstract: A void in an infinite elastic-plastic material grows without bound when a cavitation stress limit is reached. Such unstable void expansion, driven by the elastic energy stored in the surrounding ...

Abstract: Two examples illustrate the propagation of instability modes under quasi-static, steady-state conditions. The first is the inflation of a long cylindrical party balloon in which a bulge propagates ...

Abstract: A study is carried out of the problem of a penny-shaped crack in an infinite body of power-law material subject to general remote axisymmetric stressing conditions. The plane strain version ...

Abstract: Fully plastic plane stress solutions are given for a center-cracked strip in tension and an edge-cracked strip in pure bending. In the fully plastic formulation the material is characterized ...
