Reduced Experimental Stress-Strain Results for a Low-Strength Concrete under Multiaxial States of Stress.

摘要

Results of an experimental program on low-strength concrete under multiaxial states of stress were evaluated for consistency and for baseline shifts. After adjustments to the data had been made, various plots of the experimental results were prepared. Loading paths and limit points are shown in plots of stress and strain, pressure and volumetric strain, three stress invariants, and three inelastic strain invariants. The result is a set of curves that are beneficial for developing and evaluating constitutive models. (Author)
