Notable Projects
Implemented the non-ordinary state based peridynamic method into the Sandia National Laboratories developed transient dynamic computer program EMU. This new method was then employed with the
Boeing Company’s strain invariant failure theory (SIFT) to simulate the deformation and fracture of
epoxy/carbon fiber composite materials.
Developed analytical and computational models to describe the physics of the deformation and
fracture of fiber reinforced composite materials subjected to dynamic loadings.
Developed analytical and computational models to describe the physics of the deformation of solid
materials, creating tools to be used in designing projectiles for penetrating solid materials.
Established an expert system to assess damage to mission critical facilities, and propose a method of
repair based on available materials as well as determine required manpower.
Designed an anchored wall panel system for soil reinforced facilities by using an analytical model to
describe the explosive ground shock response of an anchored wall system.
Identified a rational relation between the observable and measurable micro- and macro-scale
properties of a fiber-matrix interface to determine durability of a fiber reinforced composite system.
Conducted undergraduate training sessions to teach students to solve statistics and dynamics problems.
Professional Synopsis
President Thomas L. Warren, Ph.D. 2006-present
Contractor to the Boeing Company working on developing more robust carbon reinforced epoxy matrix
composite materials for use with the Boeing 787 aircraft.
Contractor to the Institute for Advanced Technology (IAT) at the University of Texas at Austin. This
work involved consulting on using the peridynamic method for solving cavity expansion problems.
Additional analytical and numerical work has also been done in the area of penetration and perforation
of assorted target materials.
Senior Member of Technical Staff SANDIA NATIONAL LABORATORIES 1997-2005
This work utilized a combined experimental, analytical, and computational program to study the
mechanics of penetrator-target interactions. This enhances the ability to design and predict the
performance of penetrating or perforating projectiles over a large range of velocities in several
different types of targets. Significant improvements in both analytical and numerical methods
over the last several years due to this work has greatly improved the predictive capability of
penetration events through the use of numerical simulations.
Postdoctoral Appointee SANDIA NATIONAL LABORATORIES 1995-1997
Postdoctoral appointee to Dr. Michael J. Forrestal. This work involved a combined experimental, analytical, and computational program to study the mechanics of penetrator-target interactions in
order to improve the ability to design and predict the performance of penetrating or perforating
projectiles at different velocities in several different types of targets.
Research Assistant Arizona State University 1991-1995
Research Assistant to Professor Dusan Krajcinovic. This involved establishing a combined experimental, analytical, and computational program to obtain a rational relation between the observable and measurable micro-scale properties of a fiber-matrix interface, and the macro-scale properties such as strength and toughness of a fiber reinforced composite system.
Staff Engineer APPLIED RESEARCH ASSOCIATES, INC. 1989-1991
Developed a system for use with post-attack damage assessment of mission critical facilities based on the
C Language Integrated Production System (CLIPS) produced by NASA.
Prior to 1989, held positions as a Teaching Assistant in theCivil Engineering Department and a Research Assistant to Professor J.D. Achenbach at NORTHWESTERN UNIVERSITY.
