In retrospect, even the rapid progressions from uncomplicated influenza infec-tions to fatal pneumonia, a hallmark of the 19181919 fall and winter waves, had been noted in the relatively few severe spring wave cases. The differences between the waves thus seemed to be primarily in the much higher fre- 5.

Localised strain-hardening using an indentation tool was observed to cause small Hip Strains - OrthoInfo - AAOSA hip strain occurs when one of the muscles supporting the hip joint is stretched beyond its limit or torn. Strains may be mild, moderate, or severe, depending on the extent of the injury. A severe strain can limit your ability to move your hip.

Digges Inhomogeneous Strain Distribution in SiCf/SiC Coupons Aug 17, 2017 · The complex structural architecture and inherent processing artefacts within ceramic matrix composites combine to induce inhomogeneous deformation and damage prior to ultimate failure. Bulk measurements of strain via extensometry or even localised strain gauging will fail to characterise such inhomogeneity when performing conventional

Jan 01, 2019 · Localised prior strain-hardening inhibited tearing initiation in the specimens used for this study. However, several factors limit the range of situations where it could produce a beneficial effect on a material's apparent tearing resistance.

Oct 26, 2015 · Strain theories argue that strains or stressors are a major cause of crime. Individuals engage in crime to reduce or escape from strains (e.g., theft to reduce monetary strain, running away to escape abusive parents), seek revenge against the source of their strain or related targets, or cope with the negative emotions caused by strain (e.g., illicit drug use). Stress and strain:Mechanical properties of materialsMar 08, 2019 · Offset yield strength is the stress that will cause a specified amount of permanent strain (typically 0.2 percent). It is found by drawing a line that crosses the X (strain) axis at 0.002 and runs parallel to the stress-strain line (slope = E). The point where this line intersects the stress-strain curve is the offset yield point.
