The axial compression for a rock pillar indicated the peak and residual strengths increase six-fold when the soft rock interlayer approached the vertical and the effect of the intermediate principal stress is taken into account. 展开 关键词: soft rock strength strain-softening complex stress state ...
When dealing with the mechanics of materials, it is essential to understand the various measures of stress and strain that can affect materials under different loading conditions. Two of the most comm
Yu Wang, in Materials & Design, 2021 2.1.1 Principal stress lines PSL is defined as two orthogonal curves which are numerical integrations of principal stress directions in the design domain [38,41], so that any 2D elementary section or 3D volume orientated along PSL will be subjected to ...
1.Biaxial compressive test apparatus,test techniques and test results of rock materials are reviewed in the paper,and pointed out shortcomings such as most current failure criteria ignore the affection of intermediate principal stress,samples too small to assess the scale effects and the friction betwe...
This theory simply asserts that yielding occurs when the largest principal stress equals the yield strength. Stresses in the other directions are disregarded for this criteria. Only the maximum principal stress must be determined to apply this criterion. This theory is used for biaxial states of ...
In order to investigate the effect of principal stress orientation on the stability of regular tunnels and cracked tunnels, experiments by using square specimens with a centralized small tunnel were conducted, and the corresponding numerical study as well as photoelastic study were implemented. Two kind...
The training also needed to find those who could___in an environment of stress, mess, failure and hardships. To me, the basic training was a lifetime of challenges that lasted six months. And today, I’d like to talk about one little thing, which I think is one of the most important...
