A new optimization concept is introduced which involves the gradient-based optimization of any nonlinear structure by using gradients calculated from a linear equivalent, leading thus to significant computational savings compared to the classical Newton-type optimization algorithms which require gradient information from the nonlinear structure itself.
SPIE 2018 Behavior and Mechanics of Multifunctional Materials and Composites XII (SSN04) conference will be held in Denver, Colorado, United States on March 4 to 8 2018, as a part of SPIE Smart Structures + Nondestructive Evaluation.
Topics of interest are broadly grouped into the following categories:
• functional soft materials and structures
• mechanics of smart and multifunctional materials
• modeling and simulation of smart and multifunctional materials

Mississippi State University, Mechanical Engineering department is seeking outstanding candidates for the project “Theoretical Understanding of Porosity-Induced Mechanisms during Solidification of Cast Alloys and their Influence on Process-Structure-Property Correlations”, which is funded by a NSF grant.
This paper summarizes the development of an object-oriented C++ library for the virtual element method (VEM) named Veamy, whose modular design is focused on its extensibility. The two-dimensional linear elastostatic problem has been chosen as the starting stage for the development of this library. In contrast to the standard finite element method, the VEM in two dimensions uses polygonal finite element meshes.
There has been a strong and recent research activity to obtain tunable wrinkling patterns in film/substrate systems, which proposes to use geometric curvature as a control parameter. This paper studies core-shell cylindrical systems under thermal loads, with the aim to describe possible wrinkling modes, bifurcation diagrams and dimensionless parameters influencing the response of the system.
<p>Applications are invited from suitably qualified candidates for two full-time Postdoctoral Researcher positions on the finite element simulation of magnesium orthopaedic implants. These three year fixed term positions are funded through a US-Ireland R&D Partnership Programme involving collaboration between the SFI Centre for Research in Medical Devices (Cúram), the NSF Engineering Research Centre Revolutionizing Metallic Biomaterials (RMB, USA), and the Nanotechnology and Integrated Bioengineering Centre (NIBEC, Northern Ireland).

The effect of simultaneous alignment of polyethylene (PE) lamellae and graphene nanoplatelets (GnP) on thermal conductivity (k) of PE-GnP composites is investigated. Measurements reveal a large increase of 1100% in k of the aligned PE-GnP composite using 10 weight% GnPs relative to unoriented pure PE. Rate of increase of k with applied strain for the pure PE-GnP composite with 10 wt% GnP is found to be almost a factor of two higher than the pure PE sample, pointing to the beneficial effect of GnP alignment on k enhancement.
