Special Issue Information

Dear Colleagues,

Engineering plasticity is a vibrant branch of research that opens new fields of interest. In recent years it was strongly enriched by fast dynamic loadings. This direction of scientific activity is generated by the needs of applications in different branches of industry (aviation, space engineering etc.). In this Special Issue we plan to collect new ideas in engineering plasticity and impact dynamics, two fields which have recently proved indispensable in a range of applications.

The submitted papers should be focused on the plastic behavior of materials and structures in the wide range of rate of deformations and temperatures. Theoretical, numerical and laboratory studies are welcome. Studies may be enriched by industry applications, where a main focus could be the determination of structural safety, measured by possible fracture and damage. In particular, topics of interest include the fascinating behavior of materials under impact loading when the rate of deformation is more than 100 s−1, as well as the design of new materials (often composites) which are resistant to these loadings and can serve as protective materials and structures.

Deck structures subjected to drop-weight low-velocity impact are critical safety elements for ships and offshore structures. Therefore, the aim of the present study is to propose experimental research on dynamic responses of deck structures composed of stiffened plates subjected to drop-weight impact of a wedge impactor. The first step was to fabricate a conventional stiffened plate specimen and a strengthened stiffened plate specimen, as well as a drop-weight impact tower. Then, drop-weight impact tests were carried out. Test results show that local deformation and fracture occurred in the impact area. A sharp wedge impactor caused premature fracture, even under relative low impact energy; the permanent lateral deformation of the stiffened plate was reduced by 20–26% by the strengthening effect of a strengthening stiffer; residual stress and the stress concentration of the cross-joint caused by welding may cause undesired brittle fracture. The present investigation provides useful insight for improving the crashworthiness design of the deck structure of ships and offshore structures. Full article
