The micromechanics code MUL2-UC is developed to work as an efficient and high-fidelity tool for the computation of the effective stiffness matrix and the recovering of the local fields of periodically heterogeneous composite structures. The main novelty is that higher-order beam theories are employed to model the microstructure of composite structures, differing from conventional micromechanics numerical tools which usually make use of 2D/3D finite models to solve the problem. The code implements the Mechanics of Structure Genome (MSG)  to decouple the multiscale problem into global and local analyses, and uses the Carrera Unified Formulation (CUF)  to generate lower-cost refined beam models to solve the constitutive problem posed by MSG.
The current version of MUL2-UC available here is released on 6/13/2017 on occasion of the Travel Scholarship and Code Competition of the 32nd ASC Technical Conference held in Purdue University, 23-25 October, 2017.
