Topology optimization of multi-material negative Poissons ratio metamaterials using a reconciled level set method
TL;DR: The proposed method simplifies the multi-material topology optimization by evolving each individual material with a single level set function and reconciling the result level set field with the MerrimanBenceOsher (MBO) operator.

Response of a Double Hypar Fabric Structure Under Varying Wind Speed Using Fluid-Structure Interaction
TL;DR: In this article, the effect of wind on TENSILE FABRIC STRUCTURES (TFS) is investigated by using computational fluid dynamics (CFD) and simulation.
Sliding Mode Observers for Distributed Parameter Systems: Theory and Applications
TL;DR: The theory of sliding mode and variable structure systems are employed in order to design observers for different classes of distributed parameter systems such as advection equation, Burgers’ equation, Euler equations, etc.
Dynamic Finite Element Investigation of Wave Attack on Sea Dikes: A Coupled Approach using Plate and Volume Elements
TL;DR: In this paper, a structural plate element is developed based on the Kirchhoff thin plate bending theory for modeling thin layer materials instead of the volume element, and the results of the bending moments and stresses in the bituminous concrete, as well as the excess pore pressures and displacements in the soil, are presented.

A parallel algorithm for deformable contact problems
TL;DR: A Dirichlet-Neumann type parallel algorithm for the numerical solution of nonlinear frictional contact problems, putting a strong focus on its computational implementation and its parallel behaviour and performance in both validation and realistic test cases executed in HPC machines using several processors.
