Compatible-Strain Mixed Finite Element Methods for Incompressible Nonlinear Elasticity

We introduce a new family of mixed finite elements for incompressible nonlinear elasticity — compatible-strain mixed finite element methods (CSFEMs). Based on a Hu-Washizu-type functional, we write a four-field mixed formulation with the displacement, the displacement gradient, the first Piola-Kirchhoff stress, and a pressure-like field as the four independent unknowns. Using the Hilbert complexes of nonlinear elasticity, which describe the kinematics and the kinetics of motion, we identify the solution spaces of the independent unknown fields.

PhD/post-doc on development of complex geometry reduced order models for multi-scale permeability simulation

This research focuses on the development of model order reduction methods to speed up the (repeated) multiscale prediction of permeability in composite manufacturing processes. The permeability of a composite material has a very large impact on the production process of components. It is therefore required to have an accurate knowledge and understanding of the permeability, which depends on the micro- and meso-scale geometry, in order to have a robust manufacturing process.

An asymptotic numerical method for continuation of spatial equilibria of special Cosserat rods

We present an efficient numerical scheme based on asymptotic numerical method for continuation of spatial equilibria of special Cosserat rods. Using quaternions to represent rotation, the equations of static equilibria of special Cosserat rods are posed as a system of thirteen first order ordinary differential equations having cubic nonlinearity. The derivatives in these equations are further discretized to yield a system of cubic polynomial equations.

New book on "Probabilistic Mechanics of Quasibrittle Structures: Strength, Lifetime, and Size Effect" by Zdeněk P. Bažant (Northwestern University) and Jia-Liang Le (University of Minnesota), Cambridge University Press 2017

Quasibrittle materials are becoming increasingly important for modern engineering. They include concretes, fiber composites, tough (coarse-grained) or toughened ceramics, rocks (including shale), sea ice, wood, carton, stiff soils, rigid foams, glass, bone, dental and biomaterials, as well as all brittle materials on the micro or nano scale. Their salient feature is that the size of fracture process zone is non-negligible compared to the structural dimensions.

New postdoc opening in topology optimization in thermomechanical problems in Cardiff University, UK, with Rolls Royce

Applications are sought for a Post-Doctoral Researcher at the Cardiff University, UK to join the exciting and active M2DO research lab. The primary research focus is to develop topology optimization for thermal-elastic interaction. This will be achieved by building on the level set topology optimization method that the M2DO lab has developed for mechanical and coupled problems. The application of interest is in the high temperature environment in aero-engines. The position is for two years.

Partial constraint singularities in elastic rods

We present a unified classical treatment of partially constrained elastic rods. Partial constraints often entail singularities in both shapes and reactions. Our approach encompasses both sleeve and adhesion problems, and provides simple and unambiguous derivations of counterintuitive results in the literature. Relationships between reaction forces and moments, geometry, and adhesion energies follow from the balance of energy during quasistatic motion. We also relate our approach to the configurational balance of material momentum and the concept of a driving traction.
