Let us understand the modulus of elasticity using examples in this post. The modulus of elasticity is a measurement of the object's stress–strain relationship. The modulus of elasticity is the most important factor in calculating the deformation response of concrete when stress is applied. Elastic...
Once the strain tensor is defined, one needs to use the constitutive relation which at linear level relates the strain tensor to the stress tensor \sigma_{ij}: \begin{equation}\sigma_{ij}\,=\,C_{ijkl}\,\varepsilon^{kl}\,+\,\dots, \tag{13}\end{equation} with C_{ijkl} being ...
Aiello and Ombres [36] analyzed the cracking and deformation properties of beams reinforced with CFRP sheets and established a theoretical model for predicting the crack width and deformation based on a cracking analysis founded on slip-bond stress. Zhuang et al. [37] examined the effect of CFRP...
The model is formulated in the conventional triaxial stress space. The mean effective stress p=(σa+2σr)/3 and deviatoric stress q=σa−σr are stress quantities, while the volumetric strain εp=εa+2εr and deviatoric strain εq=2(εa−εr)/3 are strain quantities. The subscript...

This article further discus-Ses reliability calculation of the Simple Rigid Frame in the stress redistribution case. We obtain reliability calculation formulas of the Simple Rigid Frame structural system, and give numerical example in the Normal-normal case.关键词:...
Two equivalent formulas for the longitudinal displacement profile in squeezing ground considering finite strain are proposed. The applicability of displacement-release coefficient by small strain analysis for quantifying the stress relief to squeezing ground is obtained....
