Modelling of fracture in pressure vessels by thin shell isogeometric analysis

We aim to model fracture on pressure vessel surfaces so that its rupture can be avoided. It is well known that pressure vessels have wide-spread applications in almost all industries. They are often subjected to high pressures and extreme temperatures and in some typical applications they even carry highly flammable or hazardous substances. In the presence of cracks, the state of stress near the fracture zone becomes very high, due to the...
