A novelty FG honeycomb-reinforced laminate (FGHRL) with viscoelastic material is constructed for an industrial exoskeleton. The study examines how FGHRL dissipates energy under hygrothermal conditions. Low-velocity impacts on the exoskeleton's load-bearing structure are simulated using a spherical object. Parameters FGHRL, made of two-phase material, estimated Halpin-Tsai model and macroscopically uniform theory. In-plane deformations determined Reddy's HSDT, while impact response evaluated...
Abstract We exploit level-set topology optimization to find the optimal material distribution for metamaterial-based heat manipulators. The function, geometry, and solution field are parameterized using Non-Uniform Rational B-Spline (NURBS) basis functions take advantage of easy control smoothness continuity. In addition, NURBS approximations can produce conic geometries exactly provide higher efficiency higher-order elements. values function at points (called expansion coefficients)...

The thermal conductivity of Functionally Graded Materials (FGMs) can be efficiently designed through topology optimization to obtain meta-structures that actively steer the heat flow. Compared conventional analytical design methods, allows handling arbitrary geometries, boundary conditions and requirements; producing alternate designs for non-unique problems. Additionally, as far is concerned, does not need intuition-based coordinate transformation or form invariance governing equations, in...
An adaptive phase field method is proposed for crack propagation in brittle materials under quasi-static loading. The refinement based on the recovery type error indicator, which combined with quadtree decomposition. Such a decomposition leads to elements hanging nodes. Thanks polygonal finite element method, nodes are treated as and do not require any special treatment. mean value coordinates used approximate unknown variables staggered solution scheme adopted compute displacement variable....
There has been a growing interest in controlled heat flux manipulation to increase the efficiency of thermal apparatus. Heat manipulators control and manipulate flow. A key effective performance these is their design. Such designs can be achieved by periodic assembly unit cells (known as metamaterials or meta-structure), whose geometry material properties optimized for specific objective. In this work, we focus on metamaterial-based such concentrator (which concentrates specified region...
