Live in-person introductory training course. This four-day course provides guidance in the use of the Itasca codes PFC2D and PFC3D to simulate the mechanical behavior of granular and solid materials.
The model is a relatively simple, total stress model, developed at the University of British Columbia for dynamic analyses of soil subjected to earthquake loading, intended to be used with undrained strength parameters in low permeability clayey and silty soils, in highly permeable granular soils, where excess pore water would dissipate as generated, or in non-saturated granular soils. Its characteristics include reduction in secant modulus with strain, emulation of marching or ratcheting to occur when there is a static shear bias, and the option of allowing a permanent modulus reduction as a function of maximum past shear stress ratio.
