In this paper, a validation study of recently proposed rate-dependent shell element fracture model using quasi-static and dynamic impact tests on square hollow sections (SHS) made from offshore high-tensile strength steel was presented. A forming limit curve used to predict the membrane loading-dominated failure, while ductile locus applied for predicting failure governed by bend loading. The p...

It is generally accepted that neutron stars form in core collapse events that are accompanied by a supernovae (types II or Ib or Ic). Typical progenitors are, therefore, larger than ∼ 2.1M⊙. We suggest [1, 2] that the binary pulsar J0737-3039 provides evidence for a new formation channel: collapse of a light progenitor. This binary pulsar J0737-3039 has several remarkable features including amo...
