Abstract: The effect of initial imperfections in geometry on the plastic buckling of simply supported compressed rectangular plates is examined. The analysis, which is based on the application of a ...

Abstract: A new, general criterion is proposed for multiaxial low-cycle fatigue failure. Contours of constant fatigue life on a plot of maximum shear strain against the tensile strain acting normal to ...

Abstract: The effects of material strain-rate dependence on necking and neck propagation in polymeric fibres are analyzed. Using a finite element scheme together with an elastic-viscoplastic constitutive ...

Abstract: The small-deflection behavior of inelastic membranes supported along arbitrary contours and subjected to lateral pressure is considered. Hill and Storåkers’ (1980) solution for isotropic power-law ...

Abstract: An effective method for strengthening existing concrete beams in bending consists in bonding fiber-reinforced composite laminates on the tension faces of the beams. Laboratory tests on beam specimens show, however, that ...

Abstract: The behavior of elastic-plastic plate and shell structures under repeated loading is considered. The typical problem is formulated in incremental or “rate” form, and a variational method is ...

Abstract: The effect of repeated loading on the yield surface is investigated experimentally for an aluminum alloy. Initial yield surfaces under combined axial stress and torsion are first obtained, and ...

Abstract: The plastic strain energy required for failure in low-cycle biaxial fatigue is estimated using the energy in uniaxial fatigue and assumptions from the theory of plasticity. A criterion for ...
