Failure prediction of marine non-planar composite π joints based on combined 2D material model and progressive damage method

Non-planar composite π joints are receiving increasing attention in marine engineering. Efficient two-dimensional (2D) finite element (FE) methods, which can accurately predicted the failure behavior of this kind of joint, are critically meaningful for structural design emphasizing low computational time and easy operation. A material model is developed here, from which the equivalent engineering constants of plies with various angles can be...
