A user-friendly plug-in for the computation of 3D stresses in generic laminated structures using ABAQUS and NASTRAN based software is here presented. The proposed approach merges the efficiency and accuracy of refined laminate theories for composite analyses and the scalability of global/local approaches. The tool has a graphical user interface (GUI) within ABAQUS and FEMAP and can be used as a stand-alone software with all the NASTRAN based tools. The tool provides 3D results across the stack of plies directly from the same display. Making use of the element-wise (EW) approach the user needs to select the shell elements in which the 3D solutions are of interest. The code automatically manages all the inputs and boundary conditions for the local solver that in the plug-in package referred to as MUL2@GL.
