John Raymond Willis

Professor John Raymond Willis is a faculty member at the University of Cambridge's Department of Applied Mathematics and Theoretical Physics (DAMTP). His research focuses on theoretical and applied mechanics, with expertise in wave propagation through complex materials, fracture mechanics, composite material behavior, and strain-gradient plasticity. He maintains an office at DAMTP (Room H0.02) and can be contacted via his university email.

Willis's research interests span:

• Wave dynamics in random composites and metamaterials
• Energy transmission/reflection at material interfaces
• Homogenization techniques for heterogeneous materials
• Fracture mechanics and corrosion-driven crack propagation
• Nonlinear constitutive modeling of composites
• Strain-gradient plasticity theory

His publications (2015-2025) demonstrate consistent focus on wave-material interactions in complex media, with recent work expanding into acoustic metamaterials and advanced homogenization techniques. Theoretical foundations are frequently applied to practical problems in material design and structural integrity.
