Shear strength for rock joints with irregular shaped asperities.

Shear Strength of Rock Joints Based on Quantified Surface Description

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...

Strength of arch-shaped members in bending and shear

Arch-shaped members are widely used for construction of tunnels, bridges, silos and shells. These members are not typically provided with transverse reinforcement and may thus have a brittle behaviour at failure. When subjected to bending or shear, traditional design methods used for straight members are not applicable due to deviation forces developing at the curved chords carrying compression...

Two-Dimensional acking For Irregular Shaped Objects

Packing problems arise in a wide variety of application areas. The basic problem is that of determining an efficient arrangement of different objects in a region without any overlap. The simplest packing problem is rectangular packing, where both the objects and the region are rectangular. Many research works have been done on two and three dimensional rectangular packing. However there are man...
