Structural Finite Element Analysis of REBCO Tape Delamination with Solid-Shell Element under Various Loads

Abstract Structural Finite Element Analysis was performed to study the delamination behaviour of layer laminated REBCO tapes using a Solid-Shell element under various loading conditions, including (1) transverse tensile delamination, (2) shear and (3) peeling delamination. A is well suited simulate tape because material thickness all layers can be specified within single element. The results obtained from models utilizing elements are compared more computationally intensive method known as Cohesive Zone Method (CZM), which has successfully modelled initiation propagation REBCO’s [1]. show that stress state in directions accurately captured by proposed employing if measured experimentally for specific used failure criteria. In this work, criteria adopted previous experimental studies 50 MPa direction 10 direction. This work provides time-efficient modelling tool predict mitigate complex systems.
