In numerous mechanical engineering applications, the use of multiscale computational modeling and simulations is imperative. Nevertheless, the computational ...

Machine Learning (ML) driven material models have been investigated for some time now. The respective ML models can be trained outside of the Finite Element ...

A special form of failure in impact loaded Fibre-Reinforced Composites (FRP) structures is delamination, in which individual layers of a laminate get separated ...

Conventional metal deformation simulations which include microstructure evolution would not consider any initial spatial variations but assume a uniform ...

As the automotive industry and its companies start to look for sustainability, materials made of natural fibers receive a growing interest. In the present ...

Orbital debris is an increasing threat to current and future missions in low Earth orbit (LEO), and spacecraft shielding is vital for future space exploration ...

Finite element (FE) simulations with constitutive models for softening materials, such as in the case of standard continuum damage mechanics based approaches, ...

This work presents a multiscale simulation framework that will be used for the simulation and experimental validation of eigenstresses in composite materials ...

Damage and fracture are important criteria in the design of products and processes. Damage mod- els can be used to predict ductile failure in metal forming ...

The capabilities of the LS-DYNA® User Defined Features, allowing for modifications to LS-DYNA analyses, are powerful. It would be impractical to fully exercise ...
