Influence of changing loading directions on damage in sheet metal forming

Advances in Industrial and Manufacturing Engineering
The impact of the stress state on damage evolution, fracture behavior, and product performance is well understood for proportional loading. However, many complex sheet forming operations involve non-proportional loading, which affect the material's ...

Structural health monitoring using the Firefly optimization algorithm and finite elements

Revista UIS Ingenierías, 2020
In this study, a novel technique for multiple damage detection of structures using modal characterization to evaluate the dynamic response of the structure given a damage model is investigated. The damage identification problem is seen as an optimization

Characterization of Radiation Damage in Tungsten

, 2019
Tungsten as plasma-facing material of a future fusion reactor will be subjected to high-flux neutron irradiation. The defect creation and its influence on hydrogen retention in tungsten irradiated with different ions were investigated. The microstructure and hydrogen retention was studied with transmission electron microscopy, positron annihilation ...
