Dr. Feenstra specializes in computational solid mechanics and has over 20 years of experience in advanced modeling and analysis projects. The technical disciplines in which he works include linear and non-linear response of structures, foundations, and soil-structure interaction under static and dynamic loads.

Dr. Feenstra has developed constitutive models for orthotropic metals, reinforced concrete, and slurry-infiltrated micro-reinforced concrete. His experience includes evaluation and development of blast-resistant designs for structures to withstand accidental and malicious explosions using High-Fidelity Physics-Based tools such as LS-DYNA and structural tools such as SBEDS and Wingard. He has experience in vibration assessment and mitigation for vehicle-structure interaction and rider-comfort issues, and in vibration assessment for vibration-sensitive equipment in healthcare and research facilities. He also worked on projects related to vehicle crash simulations and modeling of drug-eluting stents for biomedical applications. His goal is providing clients with answers to their questions using creative solutions to model complex structures under extreme loading conditions with computational tools. He has worked with commercial finite element programs such as ABAQUS, ANSYS, LS-DYNA, and DIANA.

Dr. Feenstra’s teaching experience includes a finite element course that he developed and taught at the Civil and Environmental Engineering department at Cornell University for three semesters.

Prior to joining Exponent, Dr. Feenstra was a senior engineer in the Specialty Practices Group of AECOM. Before that, he worked for ten years as an academic researcher at Stanford University, at Delft University of Technology, and at Cornell University. He started his career in the computational mechanics group of TNO Building and Construction Research in the Netherlands where he worked on finite element program development, customer support and training, and consultancy.

Dr. Feenstra has a Ph.D. in Technical Sciences and a M.Sc. in Civil Engineering from Delft University of Technology, Netherlands.
