One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The choice of a general criterion to determine the shear strength of rough rock joints is a general problem that has been investigated for many ye...

Particle breakage is one of the issues that significantly affect strength characteristics aggregate. In this paper, pre-crushed limestone aggregate was evaluated through investigating friction angle, stress–strain behaviour, and single-particle strength. The particle phenomenon studied for samples prepared at different conditions, including non-soaked samples, water-soaked acid-soaked samples. ...

Using molecular dynamics simulations, we show that sheared solutions of cylindrical micelle-forming amphiphiles behave very differently under extreme confinement as compared to the bulk. When confined to ultrathin films, the self-assembled cylindrical micelles roll along the shearing direction and align parallel to each other with their axes along the vorticity direction, as opposed to aligning...
