Liquefied strength ratio with stress densification and low stresses

Canadian Geotechnical Journal, 2021
This paper presents a comparison of four assumptions or approaches for using a liquefied shear strength ratio for sandy soils in cases where there has been a large increase in effective vertical stress, e.g., structure raising or remedial measure, that is outside the effective stresses of the case histories used to develop the empirical liquefied ...

Population stress and the Swedish sex ratio

Paediatric and Perinatal Epidemiology, 2005
SummaryWell‐developed theory implies that the human secondary sex ratio moves inversely over time with the level of anxiety and depression in the population. Few tests of this hypothesis, however, appear in the voluminous literature concerned with the sex ratio. These tests, moreover, employ designs that allow only weak inference.

Problems in the Ratio Measurement of Life Stress

Journal of Health and Social Behavior, 1976
The development and use of Holmes and Rahe's Social Readjustment Rating Scale is examined. The scale is regarded as a laudable attempt at ratio measurement and as deserving more attention and emulation in sociology than it has received. However, there are problems with the work of Rahe and his associates.

Influence of stress ratio and material properties on effective stress range ratio and crack growth

Engineering Fracture Mechanics, 1989
Abstract The influence of stress ratio R and yield strength σ y on crack closure and fatigue crack growth were studied. Crack closure and crack growth experiments were performed on 6063-T6 and 6061-T6 Al-alloys of 0%, 2%, 3% and 6% prestrains. Crack closure stresses were measured using a side edge measurement technique with a clip on
