Global Solution Branches of Forced Nonlinearly Elastic Single-Director Surfaces

Timothy J. Healey

We prove the existence of classical solutions for nonlinearly elastic, single-director surfaces or shells characterized by finite mid-plane strains and curvature. We employ topolog…

Sharp-interface limits for brittle fracture via the inverse-deformation formulation

Timothy J. Healey, Roberto Paroni, Phoebus Rosakis

We derive sharp-interface models for one-dimensional brittle fracture via the inverse-deformation approach. Methods of Gamma-convergence are employed to obtain the singular limits…

Nonlinearly Elastic Maps: Energy Minimizing Configurations of Membranes on Prescribed Surfaces

Timothy J. Healey, Gokul G. Nair

We propose a model for nonlinearly elastic membranes undergoing finite deformations while confined to a regular frictionless surface in . This is a physically correct…

An Existence Theorem for a Class of Wrinkling Models for Highly Stretched Elastic Sheets

Timothy J. Healey

We consider a class of models motivated by previous numerical studies of wrinkling in highly stretched, thin rectangular elastomer sheets. The model used is characterized by a fini…

Nucleation and development of multiple cracks in thin composite fibers

Arnav Gupta, Timothy J. Healey

We study the nucleation and development of crack patterns in thin composite fibers under tension in this work. A fiber comprises an elastic core and an outer layer of a weaker brit…

Energy Minimizing Configurations for Single-Director Cosserat Shells

Timothy J. Healey, Gokul G. Nair

We consider a class of single-director Cosserat shell models accounting for both curvature and finite mid-plane strains. We assume a polyconvexity condition for the stored-energy f…
