What is Dr. Layer?
Dr. Layer is a computer program designed to help illustrate the behavior of shear waves in layered media. The primary application area is geotechnical engineering, but geologists and seismologists may find some value in this site, as well. In its current incarnation, the program is most suitable for instructional purposes, but it may evolve into a form suitable for more general analysis at a later date.
What does Dr. Layer do?
Dr. Layer provides an interactive, quasi-real-time environment for analyzing and visualizing the propagation of 1D shear waves in linear and nonlinear layered soil masses. The screen shot below gives an impression of the range of modeling and visualization capabilities, but a quick overview of the User's Guide will give a more complete picture of the program's modeling capabilities. In short, the program has been designed to be simple to use, but still provides quite general modeling and visualization capabilities.
What else is on this site?
In addition to Dr. Layer, this site contains a full set of exercise and tutorial materials focused on learning about wave propagation. These materials are structured around Dr. Layer, and are set up to encourage self-study and hands-on exploration. The target audience for these materials is senior or graduate-level students interested in studying wave propagation in soil and rock masses, but many of the phenomena and concepts presented are generic to wave propagation in general.
Who is responsible for this site?
Dr. Layer and the supporting materials were developed by Pedro Arduino, Greg Miller, and Ayokunle Ogunrinde in the Department of Civil and Environmental Engineering at the University of Washington under the auspices of the Pacific Earthquake Engineering Research (PEER) Center.
