Ernesto A. Estrada, Ph.D.
Senior Associate
Mechanical Engineering
Atlanta

Dr. Estrada is a mechanical engineer specializing in solving problems related to structural mechanics, mechanical design, and failure. He has experience conducting stress analysis using computational and experimental techniques, including non-linear Finite Element Analysis (FEA). While at Exponent, he has solved problems in a wide array of applications, including consumer electronics, medical devices, railcars, industrial equipment, and consumer goods. He has provided services in design evaluation and optimization, and in root cause failure analysis for clients in product development, and in litigation contexts. Dr. Estrada is also an aerospace engineer with experience on aircraft stability, performance, and design.

Prior to joining Exponent Dr. Estrada was a Research Assistant at Georgia Institute of Technology. He researched the constitutive behavior of nickel-based superalloys with an emphasis in thermomechanical fatigue and in creep-fatigue interactions. Dr. Estrada used mechanical testing, optical microscopy (OM), and scanning electron microscopy (SEM) to characterize the material behavior of superalloy CMSX-8. He used experimental observations and theory to develop and implement microstructure-sensitive crystal viscoplasticity models in Abaqus FEA through a User Material Subroutine (UMAT). Dr. Estrada used these models to predict the inelastic deformation of superalloys at extreme temperatures ranges.
