Elastic-Plastic Deformation of Pulse-Loaded Structures.
Abstract
The research aimed to provide a simple but realistic approximation technique for the plastic deformation and maximum deflection of a structure subjected to a general pulse loading. We are considering structures such a beams, frames, plates, and shells; of ductile metal either rate independent or rate sensitive (steel, titanium). Other materials such as reinforced or pre-stressed concrete and fibre-reinforced materials, may be treated by extensions of the new methods. The work has been concerned with the analysis of deformations due to force pulses of general shape, finite duration, and force magnitudes ranging from near the static collapse value to several multiples of this. The work hs involved (a) laboratory experiments, (b) complete finite element numerical solutions by ABAQUS, and (c) the extension of the three-stage simplified elastic-plastic approach to such problems.
