... on page 70 properly displays the concept of slip-stick. Equation 3.31 on page 71 tells us that F = F 1 when κ Δ ν / ν = 1 . However, the value of F / F 1 on the thick curve in Fig. 3.9(b) is not equal to 1 at κ Δ ν / ν = 1 . Also the μ R...

.... A common feature is that undrained response, invoked by rapid slip or deformation, is stiffer than drained response, which occurs for slower slip or deformation. The time and spatial variation of the stress and pore pressure is different for slip on permeable and impermeable planes. These solutions...
