Research Interests

Dr. Allen's research focuses primarily on modeling of the mechanical response of viscoelastic and viscoplastic media to both mechanical and thermal loadings. Depending on the applications, this may include dissipation due to phase changes and/or fracture, including multiple simultaneous growing cracks. Much of his research deals with predicting failure due to either long term cyclic loading, or short term impact loading. Recent applications studied by Dr. Allen include prediction of the response of tank armor to ballistic impact, life of asphaltic pavement due to repeated tire loadings, failure of metal matrix composites due to oxidation induced fracture, and fracture induced failure of abdominal aortic aneurysms.
