The Limitations of Dynamic Formulae
In an earlier post Vulcan's advice on the limitations of dynamic formulae--specifically referencing the Engineering News Formula--was set forth. That advice appeared in Vulcan's literature from 1906 to 1931. Later in the 1930's Vulcan changed the way its literature was organised, and in the process Vulcan added new verbiage (a lot of it, really) to … Continue reading The Limitations of Dynamic Formulae

Is the Best Place to Run Old Windows Software…on Linux or a Mac?
A few years ago I put out an article entitled Partying Like It’s 1987: Running WEAP87 and SPILE (and other programs) on DOSBox, where I describe the use of DOSBox in running engineering software (and also Windows 3.1.) A great deal of engineering software developed in the DOS era can still be used for engineering design … Continue reading Is the Best Place to Run Old Windows Software…on Linux or a Mac?
STADYN Wave Equation Program 11: Application of the STADYN Program to Analyze Piles Driven Into Sand — vulcanhammer.net
The newest update for the STADYN research project is available: Download Application of the STADYN Program to Analyze Piles Driven Into Sand The abstract is as follows: Abstract: The STADYN program was developed for the analysis of driven piles both during installation and in axial loading. Up until now the test cases used were in […] … Continue reading STADYN Wave Equation Program 11: Application of the STADYN Program to Analyze Piles Driven Into Sand — vulcanhammer.net
Picking Up Concrete Piles for Driving
One of the concepts students in geotechnical engineering courses seem to have the most trouble with is estimating stresses in concrete piles during pick-up and setting them in place to drive. The basic problem is that it's sometimes hard to get our heads around the analytical simplification of the actual situation. Let's start by looking … Continue reading Picking Up Concrete Piles for Driving
A Sea Fight in a Fog: Revisiting the ASCE Controversy about Dynamic Formulae
It's always good for geotechnical professors and practitioners alike to think about where our industry has been and where it’s headed. A little while back three of our most eminent people (Garland Likins, Bengt Fellenius and Robert Holtz) came together and wrote an excellent piece for the 2Q 2012 issue of the Pile Driver (the … Continue reading A Sea Fight in a Fog: Revisiting the ASCE Controversy about Dynamic Formulae
Partying Like It’s 1987: Running WEAP87 and SPILE (and other programs) on DOSBox
It’s been a long time since many computers ran DOS or even Windows 3.1. Given the changes in hardware, it would be difficult to get most any recent PC to run one or both. Yet every time we have a major software upgrade, we lose some of the capabilities we had in the past. It’s … Continue reading Partying Like It’s 1987: Running WEAP87 and SPILE (and other programs) on DOSBox
Vulcan Hammers and the Gates Formula
For many years, Vulcan included Engineering News Formula charts and data in its literature. Vulcan dropped the EN formula out of its literature in the 1970's, for two reasons: the wave equation was in the ascendancy, and endorsement of the EN formula was an implied endorsement of the "bearing power" of the piles they drove, … Continue reading Vulcan Hammers and the Gates Formula
TAMWAVE: Cavity Expansion Theory and Soil Set-Up
One of the things that was attempted in the TAMWAVE project is the use of cavity expansion theory to estimate soil set-up in cohesive soils. Doing this, however, brought some complications that need some explanation. Cavity expansion theory is basically the study of what happens when one body expands inside of another. When this takes […] … Continue reading TAMWAVE: Cavity Expansion Theory and Soil Set-Up
