Challenging Research Thrusts
Below are some areas that I believe will be particularly fruitful and significant to pursue in the next decade:
- Deformation and failure of extruded low density cellular alloys, as well as novel new applications of these materials
- Variable resolution models (constitutive and FE modeling), and appropriate averaging approaches within ISV schemes
- Massively parallel schemes for polycrystal plasticity
- Multiscale plasticity/viscoplasticity
- Rotation and stretch fields in heterogeneous materials; micropolar theories and multiplicative decompositions
- Atomistically-consistent continuum separation laws for fracture of realistic microstructures
- Influence of pre-history and texture on ductility, fracture and fatigue
- Void nucleation in shear from inclusions
- Void cluster effects
- Void and fatigue crack growth from fractured and debonded particles
- Dynamic and static recrystallization
- Continuum models for discrete shearing in solution-strengthened systems and single crystals
- Growth of small fatigue cracks in castings from small and large scale porosity
- Engineering large pore populations in cast alloys for fatigue resistance
- Fracture of graded interfaces, including weldments, brazed and soldered joints
