Additionally, he developed a computational framework to study the influence of interfacial debonding on the macroscopic softening of particle reinforced polymers. In this field, his contributions include developing a solution for the influence of nanoscale interphases on the macroscale mechanical response of particle reinforced elastomers under large deformations. Spring’s research focused on composite materials. Additionally, he developed a new constitutive relation for crack face unloading that maintains thermodynamic consistency within the cohesive zone, which can be of particular importance when simulating fatigue crack propagation and self-healing behavior. He developed a novel method for addressing a longstanding critique of the cohesive element method-mesh dependency-through the use of adaptive topological operators on polygonal discretizations. research focused on computational fracture mechanics with an emphasis on the use of cohesive zone models for simulating quasi-static and dynamic crack propagation. As a graduate from the University of Illinois at Urbana-Champaign, his Ph.D. Spring joined the Applied Research & Development Team at E 2G in 2015 and currently serves as a Consulting Researcher.
