Eric P. Guyer, Ph.D., P.E.

Dr. Guyer’s areas of expertise include materials science, metallurgy, adhesion science and more generally failure and degradation of metals, polymers, ceramics and welded structures particularly as it pertains to fracture, fatigue, corrosion, stress corrosion cracking, and environmentally assisted cracking, hydrogen embrittlement and creep.

He has extensive experience investigating and solving complex multidisciplinary problems in: medical devices (e.g., active implantable devices, drug delivery systems, sterile pouches as well as cardiovascular and orthopaedic devices, etc.), consumer products (e.g., smart phones, photovoltaic modules, bicycles, heaters, remote controls, art work, etc.), and industrial systems (e.g. boilers, high and low pressure pipe and plumbing components, jet engine components, adhesives, etc.). These investigations are typically related to root cause analyses or product recalls.

Dr. Guyer is a NACE Certified Coatings Inspector and regularly conducts analyses of various paint and protective-coating systems applied to a wide variety of steel, aluminum, plastic, composite, wood and cementitious structures. Analyses commonly conducted involve coating selection, specification writing, and failure (delamination, cracking, blistering, chalking, discoloration, mildew, efflorescence, etc.).

He previously held two academic appointments: one in the Materials Science and Engineering Department at Stanford University where he taught the course Failure Analysis of Emerging Technologies and the other in the Mechanical Engineering Department at Santa Clara University where he taught the course Fracture and Fatigue of Materials.

Prior to joining Exponent, he was employed as a Senior Materials Engineer at Lockheed Martin’s Advanced Technology Center. His research involved the oxidation kinetics of advanced high temperature ceramics as well as the fracture, mechanical and optical properties of polymer thin-films. As an undergraduate, Dr. Guyer was employed by the Dow Chemical Corporation where he examined the mechanisms of controlled drug delivery in biodegradable, pharmaceutical grade polymers.
