Report on the dynamic strength of rigid-plastic beams under blast loads.

ResearchPublished 1956
An analysis to determine upper bounds to the dynamic strength of simply supported beams acted upon by a uniformly distributed blast pressure. Rigid-plastic behavior in bending and/or in shear (development of "plastic hinges" and/or "plastic slides") is assumed. The time variation of the blast pressure is approximated by a negative exponential time function with peak value at t = 0.
