  • Menlo Park

Dr. Davis specializes in fracture mechanics and has a strong background in computational mechanics and finite element analysis (FEA). His work has spanned a variety of materials, including experience with delaminations in carbon fiber composite laminates. Other areas of expertise include structural mechanics and mechanics of materials. Dr. Davis is also interested in leveraging state-of-the-art, multi-scale experimental observations with computational methods to improve fracture and fatigue analysis.

Dr. Davis was a member of the Cornell Fracture Group, where his doctoral research aimed to develop computational tools to simulate and predict fracture and damage in structural components. His novel simulation technique included generating complex cracked models, computing accurate fracture mechanics parameters, and employing a new formulation to calculate explicitly 3-D, crack-front evolution. Dr. Davis has extensive experience with commercial finite element software (Abaqus) and fracture analysis software (FRANC3D).

While at Cornell, Dr. Davis served as a Teaching Assistant for structural modeling and behavior classes, as well as providing formal mentorship for undergraduate research related to damage tolerance of composite materials. He has also collaborated with the Durability, Damage Tolerance and Reliability Branch at NASA Langley Research Center, and been involved in organizing a conference session for the Society of Experimental Mechanics.
