The main observed fracture mechanism for these metals was coalescence of pores and shear bands.
Finally, qualitative numerical simulations were conducted, which accurately depict the experimentally observed fracture behaviors.
The experimentally observed fracture propagation pattern is also in good accordance with those obtained by the standard finite element method.
Other surface features: On the surfaces of both Itokawa particles, we also observed fracturing, abrasion-like features, and blisters (Fig. 2).
We compared those maximum paleo-stresses to fractures interpreted in image logs and found a good correlation between maximum paleo-stress and observed fracture orientation and fracture density (Fig. 7).
For both variations in T and V, inter-trochanteric fracture situations were well demonstrated by φ as well as by SR and strain contours, similar to clinically observed fractures.
This can be achieved by conducting computer simulations of the experimentally observed fracture phenomena in polycrystalline specimens having a given texture and microgeometry.
In one of the failure modes observed, fracture occurred when the dominant fatigue crack propagated into either the magnesium or aluminum sheet in a kink-crack formation.
The models were also evaluated for their agreement between predicted fractures and observed fractures.
Agreement between predicted and observed fracture risks was close across all age groups.
Among men with osteoporosis by WHO criteria, observed fracture probabilities were greater than FRAX predicted probabilities (20.6% v 9.5% for hip fracture and 30.0% v 17.4% for major osteoporotic fracture).
