    Impact Response of a Thin-walled Beam of Open Profile.- Conclusion.- Appendix. (source: Nielsen Book Data) This short book analyses the dynamic stability with respect to small perturbations, as well as the local damage of geometrically nonlinear elastic, spatially curved, open section beams with axial precompression. “Numerical study of lap joints with composite adhesives and composite adherends subjected to in-plane and transverse loads”, International Journal of Adhesion & Adhesives, 28, , “Dynamic response of functionally graded circular cylindrical shells”, Advanced Materials Research, Vol. , , Quasi-static bending of beams () A beam deforms and stresses develop inside it when a transverse load is applied on it. In the quasi-static case, the amount of bending deflection and the stresses that develop are assumed not to change over time. In a horizontal beam supported at the ends and loaded downwards in the middle, the material at the over-side of the beam is . The first five chapters of this book introduce the rigid plastic methods of analysis for the static behaviour and the dynamic response of beams, plates and shells. These chapters develop the key features of the subject from an engineering viewpoint, and are followed by several chapters on various phenomena of importance to structural impact.

      As early as in , Menkes and Opat (Exp Mech ; –6) conducted an experimental investigation on the dynamic plastic response and failure of fully clamped metal beams subjected to a uniformly distributed impulsive loading and identified three basic failure modes: large inelastic deformation (Mode I), tensile tearing (Mode II) and transverse shear .
