Multiscale-Modeling-Enablement of Advanced Solvers
Abstract
Defense structural components are subject to extreme loading and environment settings. Such structures must, for example, resist to ballistic impact and blast waves. These advanced materials have superior performance compared to standard materials, mainly due to their microstructural details. Such advanced materials can be analyzed with MultiMech, a concurrent multiscale Finite Element code, available as stand-alone tool and also integrated into some of the mainstream commercial Finite Element platforms through its Application Program Interface (API). The API was designed in such way to work with multiple global scale solvers, not only Finite Element based codes. The purpose of this proposal is to adapt/enhance the existing Application Program Interface (API) with focus on embedding multiscale modeling into existing topology optimization code, developed/maintained by Dr. Ray Wildman at ARL. Topology optimization capabilities currently only encompass optimizing single scale models, either the global scale or the local scale separately. Through the proposed development, the solution of two-scale concurrent optimization problems will be possible.
