Litigation Support Services

At RWFE, our litigation support activities relate to our areas of expertise. We have helped clients in the past by evaluating case for potential causes of action, including products liability, negligence, warranty, and premises liability claims. We have also provided preliminary opinions on intellectual property matters, including possible infringement, potential patentability, and the value or secrecy of different processes or formulas protected as trade secrets.

Areas of Expertise

Additional Expertise:

Tribology (Friction Analysis), Tools & Equipment Safety, Hail and Wind Damage, High Speed Photography.


Professor Jahan Rasty has 25+ years of experience in engineering education, consulting, forensic engineering and expert witness litigation support.

Over the last 18 years, Professor Rasty has developed and taught 23 undergraduate and graduate level courses in the areas of Failure Analysis, Fracture Mechanics, Materials Science, Design, Metallurgy, Materials Selection and Manufacturing.

Professor Rasty has authored 71 scientific publications, 22 invited talks and lectures, and is the Principal / Co-Principal Investigator of more than $7.4 million in engineering research projects sponsored by federal and state government research entities, as well as major Hi-Tech industries.

Professional Experience

1986-Present: Real-World Forensic Engineering
Performed engineering analysis and provided expert witness testimony and consulting
services in the areas of Forensic Engineering, Mechanical Design, Failure Investigation,
Stress Analysis, Materials Characterization/Testing, and Experimental Engineering
Analysis for a number of local as well as national corporations.

1/85-7/85: ETHYL Corp., Baton Rouge, Louisiana.
Project Engineer
Evaluated the stresses and displacements of reactor vessels under operating conditions
and recommended modifications in the design of the vessels. Analysis was conducted
using the existing theoretical solutions. In addition, ANSYS Finite Element Program was
utilized to verify the theoretical results. Due to complex geometry of reactor parts being
analyzed, extensive experience in modeling of mechanical parts with complex geometry
and boundary conditions was obtained.
