TESS

This program is designed for 1D wave propogation analyses using an explicit finite difference scheme. Major components of this software include:

• Use of the HDCP soil model
• Hysteretic damping at low strains
• Modeling of degradation and degeneration of stress-strain loops for cohesive and cohesionless soils
• Calculation of redistribution and dissipation of excess pore pressures
• Compliant base and energy absorbing lateral boundaries

• Generation of output files: time histories of acceleration, velocity, displacement, shear stress, shear strain, and excess pore pressure in any layer
• Graphical animation of soil response during earthquake shaking.
• Verification against closed-form solutions and case histories
