We formulate a geometric theory of nonlinear morphoelastic shells that can model the time evolution of residual stresses induced by bulk growth. We consider a thin body and idealize it by a representative orientable surface. In this geometric theory, bulk growth is modeled using an evolving referential configuration for the shell (material manifold). We consider the evolution of both the first and second fundamental forms in the material manifold by considering them as dynamical variables in the variational problem.

Dear Colleagues,

15th European Mechanics of Materials Conference (EMMC15) will be held in Brussel, Belgium, during 7 – 9 Sentember, 2016. As part of this meeting, we are organizing a session (S7) to bring together experts in modelling, simulation, manufacturing and experimental investigation in the field of functional and architectured materials to present and discuss recent advances. Topics of particular interest include (but not limited to)

Full PhD scholarship (tuition fee plus $25,406/year stipend ) is immediately available at the School of Engineering, RMIT University, Australia. Applications are invited for one open position in one of the following areas: (1) Mechanics of carbon nanotubes and graphene; (2) Multiscale simulation of nanotubes/graphene reinforced composites; (3) Mechanical and Electrical behaviours of composite structures. The research work is supported by Australian Research Council under DECRA scheme. 

AIMS AND SCOPE

Applications are sought for four Post-Doctoral Research Associates and two PhDs to join a very active research group at Cardiff University, UK (School of Engineering).  Based in Cardiff, there will be frequent interactions with the University of California, San Diego as well as major aerospace companies in the UK. The research will formulate and develop numerical methods for mulitiscale and multiphysics design optimisation using level set topology optimization.

One or more of research experience in the following areas are required.

The Department of Aerospace Engineering at the Indian Institute of Technology, Madras is seeking to fill Assistant Professor vacancies in the following research areas.

1) Experimental Structural Mechanics/ Composites
2) Aircraft Aerodynamics (experimentalists preferred)
3) Control and Flight Mechanics of Aerospace vehicles
4) Aircraft Design (aerodynamic/structural)

Since real specimens deform three-dimensionally, 2D modeling approaches cannot predict the flow curve of the material precisely. The predicted flow curves obtained from 2D modeling can, however, be correlated to the 3D ones by introducing a correlation factor, We quantified by the stress ratio (σ_3D/σ_2D) based on the 2D and 3D RVE calculations for DP600 steels with various martensite phase fractions (V_m=0–50%) at different equivalent plastic strains varying from ε^p_eq=0 to 0.1.
