MultiMechanics, a developer of multiscale composite modelling and simulation software, has announced the release of MultiMech 19.0, a multiscale material modelling and simulation software platform that virtually predicts failure in advanced materials.

“Composite materials are currently transforming the transportation industry by improving efficiency, lowering emissions, and decreasing fuel consumption. However, the current process for adopting these advanced materials is time sensitive and can cost millions in testing and certification,” the company reports. “To help address these challenges, MultiMech 19.0 delivers new material models, new damage scenarios, faster run times, and expanded integration with commonly-used FEA systems.”

The new bi-modulus elastic model will enable engineers to better capture the mechanical behaviour of carbon fibres, according to the manufacturer. In addition to exhibiting nonlinear elastic behaviour at small deformation, carbon fibres also possess different mechanical properties in tension and compression, making them especially difficult to model and simulate.

The solver speed-up of 1.5x will allow engineers to take advantage of the accuracy of a concurrent multiscale approach while benefiting from increased speed. The Parallel runs in Optimiser will allow engineers to reduce the runtime of DoE jobs and get answers faster.

MultiMech 19.0 also implements new material and failure models, including continuum damage models for orthotropic materials and new damage laws that will allow users to capture unique material behaviour with higher accuracy. It also features improved automated time step and optional displacement convergence check, as well as the ability to check for large displacements in the nonlinear solver.

The MultiMech material database has been redesigned and enhanced to speed up the workflow. Users can now create their own database of material cards to be used with MultiMech, including material definitions for individual constituents, as well as define an entire Representative Volume Element as an entry to the material database. It is also very easy to create, import, export and share a material database with other users within an organisation.

MultiMech 19.0 includes a streamlined tool to run Dynamic Mechanical Analyzer (DMA) tests virtually. With this tool, users can easily and quickly characterize the viscoelastic behaviour of complex microstructures in all directions, at different temperatures and frequencies. Finally, with the new ANSYS DX integration, users can perform optimisation studies at both the macro and micro scale using ANSYS DX’s unique capabilities.

“As the use of material modelling and simulation software expands, material scientists are demanding more accurate results without compromising speed and functionality, as well as easier and more integrated workflows. MultiMech 19.0 marks the significant progress we have made towards closing that gap,” said Dr Flavio Souza, President & CTO of MultiMechanics.
