Die less explosive forming of circular plates is one of the most useful methods in the industries especially chemical applications. Manufacturing of large vessel's head, multilayer rings and some parts of heat exchangers are the example of applying this method. Many theoretical and experimental researches about examining the explosive forming of simple and single layer plate have been done. The...

Summary Crashworthiness analysis with the so-called explicit FE programs such as LS-DYNA [1] has reached a very mature status such that the number of real physical tests e.g. in the automotive industry has been reduced considerably. Though the element technology in the explicit programs has been mainly dictated by efficiency the quality of the results of nowadays standard crashworthiness analys...

The current study focuses on the development of a finite element model of the hip capsule ligament to represent the joint between the femur and the pelvis. The finite element model of the hip capsule is represented as comprising of eight sectors, consisting of the important ligaments in those regions of the capsule. The geometric parameters for the capsule are determined from available literatu...

Prediction of formability for sheet metal pressings has advanced to a high state of confidence in recent years. The major challenge is now to predict springback and, moreover, to assist in the design of tooling to correctly compensate for springback. This is particularly the case for materials now being routinely considered for automotive production, such as aluminium and ultra high strength st...
