Grahic Jump Location
Overall philosophy of the multi-scale analysis for incorporating basic materials research into the component design process. Here we consider only monotonic loading, although cyclic loading has also been analyzed.
Grahic Jump Location
Representative micrograph of A356 aluminum. The light matrix is Al-1 percent Si, and the dark specks are silicon particles.
Grahic Jump Location
MEAM atomistic simulation demonstrating the strength of an Al-Si interface compared to pure Si or pure Al. All materials are defect free in the present simulation. Above the plot is a representative image of the bi-crystal simulation.
Grahic Jump Location
(a) Number of damaged particles versus temperature and (b) corresponding load-displacement curves from notch tensile data (Gokhale et al. 12)
Grahic Jump Location
Micromechanical finite element simulation of effective stress contours near damaged Si particles embedded in a Al-1 percent Si matrix. The black lines indicated bonding of the Al-Si interface, while the white spaces are cracks or debonds.

(Top) Schematic mapping used to import realistic microstructural features onto a finite element grid. (Below) contour plot of volume fraction of damage (sdv 10) just before failure of the material at 12 percent strain.
Grahic Jump Location
Stress-strain curves comparing the internal state variable constitutive model to experiments at different strain rates and temperatures for A356 Al (Horstemeyer et al. 7)
Grahic Jump Location
Example of failure prediction analysis in a cast A356 automotive control arm. Sdv 13 is the void nucleation rate and sdv 14 is the damage volume fraction.
