A computational homogenization framework for soft elastohydrodynamic lubrication
(Springer, 2012)The interaction between microscopically rough surfaces and hydrodynamic thin film lubrication is investigated under the assumption of finite deformations. Within a coupled micro-macro analysis setting, the influence of ... -
Computational thermal homogenization of concrete
(2013)Computational thermal homogenization is applied to the microscale and mesoscale of concrete sequentially. Microscale homogenization is based on a 3D micro-CT scan of hardened cement paste (HCP). Mesoscale homogenization ... -
A large deformation frictional contact formulation using NURBS‐based isogeometric analysis
(John Wiley & Sons, 2011-02-23)This paper focuses on the application of NURBS-based isogeometric analysis to Coulomb frictional contact problems between deformable bodies, in the context of large deformations. A mortar-based approach is presented to ... -
A method of two-scale chemo-thermal-mechanical coupling for concrete
(CIMNE, 2011)The Alkali Silica Reaction(ASR) is one of the most important reasons to cause damage in cementitious constructions, which can be attributed to the expansion of hydrophilic gel produced in the reaction. In this contribution, ... -
Multiscale hydro-thermo-chemo-mechanical coupling: application to alkali-silica reaction
(Elsevier, 2014)Alkali-Silica Reaction (ASR) is a complex chemical process that affects concrete structures and so far various mechanisms to account for the reaction at the material level have already been proposed. The present work adopts ... -
On the optimality of the window method in computational homogenization
(2013)The window method, where the microstructural sample is embedded into a frame of a homogeneous material, offers an alternative to classical boundary conditions in computational homogenization. Experience with the window ... -
Three-dimensional mortar-based frictional contact treatment in isogeometric analysis with NURBS
(2012)A three-dimensional mortar-based frictional contact treatment in isogeometric analysis with NURBS is presented in the finite deformation regime. Within a setting where the NURBS discretization of the contact surface is ...
