An experimental investigation on the dynamic ultimate compressive strength of ship plating

The aim of the present study is to obtain experimental data on the ultimate strength of steel plates under dynamically applied axial compressive loads. A series of dynamic collapse tests were carried out on steel plate models under axial compressive loads, varying the loading speed. Based on the test results, the effect of loading speed (or strain rate) on the ultimate strength of steel plates is investigated. Relevant useful formulations for assessing the dynamic ultimate compressive strength of steel plates are also derived as a function of the strain rate by curve fitting. The test data developed are documented.
