A general theory for anisotropic Kirchhoff-Love shells with in-plane bending of embedded fibers
Thang Xuan Duong, Vu Ngoc Khiêm, Mikhail Itskov +1
This work presents a generalized Kirchhoff-Love shell theory that can explicitly capture fiber-induced anisotropy not only in stretching and out-of-plane bending, but also in in-pl…
A chemo-mechano-thermodynamical contact theory for adhesion, friction and (de)bonding reactions
Roger A. Sauer, Thang X. Duong, Kranthi K. Mandadapu
This work presents a self-contained continuum formulation for coupled chemical, mechanical and thermal contact interactions. The formulation is very general and hence admits arbitr…
Isogeometric continuity constraints for multi-patch shells governed by fourth-order deformation and phase field models
Karsten Paul, Christopher Zimmermann, Thang X. Duong +1
This work presents numerical techniques to enforce continuity constraints on multi-patch surfaces for three distinct problem classes. The first involves structural analysis of thin…
A modified Coulomb's law for the tangential debonding of osseointegrated implants
Katharina Immel, Thang X. Duong, Vu-Hieu Nguyen +2
Cementless implants are widely used in orthopedic and oral surgery. However, debonding-related failure still occurs at the bone-implant interface. It remains difficult to predict s…
