Improved Multiscale Computational Strategies for Delamination

We propose a three-scale computational strategy for the simulation of laminated composite parts modelled at the meso-scale. Two nested domain decompositions are used: a LaTIn method is employed in the inner substructuring so that the debounding behaviour is bore by the interfaces between subdomains (first scale) while the outer decomposition permits to solve in parallel the LaTIn macro (second scale) problem which grants the method its scalability, a super-macro problem (third scale) is introduced to accelerate the transmission of largest wavelength numerical information. The strategy thus teams up various levels of parallelism, which makes it well suited to modern hardware architectures.
