Numerical modeling of stress-strain behavior of composite overwrapped pressure vessel

摘要: Abstract Presented is a numerical modeling analysis of the stress-strain behavior composite overwrapped pressure vessel with metal liner loaded by internal pressure. The proposed model based on finite element method and considers elasto-plastic liner, fiber orientation angle in material contact between shell. allowed solving problems determination state, degradation fracture assessment crack-like defect liner. results revealed effect propagation initial defects shell critical size surface crack.
