Dr. Elbanna's research focuses on developing computational and analytical models for complex phenomena, such as friction, adhesion and fracture, in multi-scale systems such as crustal faults and human bone. In his work, he uses concepts from a wide variety of fields including continuum mechanics, dynamical systems, numerical analysis and statistical physics. From a fundamental point of view, processes like fracture and friction are fascinating nonlinear, and often dynamic, phenomena occurring on many scales. In practice, understanding friction and fracture is of vital importance to many engineering (e.g. fiber reinforced composites), biological (e.g. bone fracture) and geophysical (e.g. earthquake rupture) applications.
