Thermomechanical framework for modelling elastoplastic damaged materials

Metallurgical Modelling of Thermomechanical Processing

Compaction of quasi-one-dimensional elastoplastic materials

Insight into crumpling or compaction of one-dimensional objects is important for understanding biopolymer packaging and designing innovative technological devices. By compacting various types of wires in rigid confinements and characterizing the morphology of the resulting crumpled structures, here, we report how friction, plasticity and torsion enhance disorder, leading to a transition from co...

Thermomechanical Analysis of a Damaged Thermal Protection System

Thermomechanical analysis of the space shuttle tile thermal protection system (TPS) subjected to damage is conducted using the finite element method. The thermal and structural response of the damaged configurations are compared with the undamaged configuration to determine the relative effects of damage on the thermal protection capability and the induced thermal stresses in the TPS. The TPS i...

Thermomechanical Behavior of Damaged TPS Including Hypersonic Flow Effects

The thermomechanical behavior of damaged space shuttle tile thermal protection system (TPS) is considered. The effects of damage on the thermal protection capability and the induced thermal stresses in the TPS are examined by comparing the thermal and structural response of the damaged configurations with the undamaged configurations. The TPS is subjected to the re-entry heating and pressure pr...

On elastoplastic damage modelling in unsaturated geomaterials

In the context of nuclear waste disposal, the modelling of the behaviour of host rocks and soils still needs improvement. Unsaturated porous geomaterials exhibit particular behaviour when exposed to suction. Their non-linear behaviour may result from two different processes, plasticity which induces irreversible strains and damage which causes a deterioration of their elastic properties. Many e...
