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.

Inspired by the discussion with Mike Ciavarella on http://imechanica.org/node/22012, I am thinking about a journal with the following attributes:

The 22nd International Conference on Wear of Materials will take place in Miami, USA from the 14-18 April 2019.

We are still accepting Poster abstract for this event, Deadline for abstract submission: Feb 28, 2018. Abstract submission and all other inquires: amm2018 [at] purdue.edu (amm2018[at]purdue[dot]edu)

It gives me great pleasure to announce the outcome of the 2017 competition for the Eshelby Mechanics Award for Young Faculty. This award is given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. The selection committee consisted of: K. Ravi-chandar (UT Austin), Huajian Gao (Brown University), G.

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.
