Compression strength failure mechanisms in unidirectional composite laminates containing a hole [PDF]
Experiments on graphite-epoxy laminated plates containing unloaded small holes show that these laminates are notch insensitive. That is, the uniaxial strength of these laminates with small holes exceeds the strength predicted by a point stress criterion ...

Aluminum matrix composites reinforced with particles (PRAMCs) frequently develop considerable residual stresses post-quenching, which can negatively affect fatigue life and dimensional accuracy.

Stress relief at corner joint and effect of stress relief on fatigue strength.
Some series of large-scale fatigue tests have already been conducted on the longitudinal groove weld, which is familiar at the corner welded joint of box sectional members. It was cleared in these tests that the fatigue crack originated from the root blowhole and that the fatigue strength was considerably lower because of the effect of the tensile ...

Introduction: When the traditional incremental technique is used for direct placement of composite resin in a deep occlusal cavity, each increment (2 mm or thicker) is individually cured where it undergoes hardening and shrinkage.

The effect of vibratory stress on the welding microstructure and residual stress distribution [PDF]
Previous studies have suggested that weld microstructure may be modified by the presence of static stresses. In this investigation, vibratory stress was applied to mild steel specimens while they were being welded to observe its effect on the residual ...
