Estimation of Soil Stiffness and Strength Parameters from Borehole Data (Standard Penetration Test)

Posted on April 19, 2018May 8, 2018

The enclosed spreadsheet uses a macro that is capable of estimating secant Young’s modulus at 50% of ultimate shear strength (), friction angle (), and undrained shear strength () of a soil layer based on typical borehole data such as SPT blow count and unit weight. This spreadsheet can be very handy when no CPT… Read More

Application of Rayleigh Damping and Numerical Damping in Finite Element/Difference Analysis

Posted on April 9, 2018April 26, 2018

This article intends to shed light on application of Rayleigh and numerical damping in finite element and finite difference analyses. As you all know, there are two types of damping in a system subjected to dynamic loads; (1) material damping, and (2) radiation damping. Material damping is the dissipated energy due to the yielding of… Read More
