Abstract

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) [1] to decouple the multiscale problem into global and local analyses, and uses the Carrera Unified Formulation (CUF) [2] 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.
