Programming Strain Rate Dependency into Mechanical Metamaterials
نویسندگان
چکیده
This work presents an approach to introduce significant strain rate sensitivity into metallic metamaterials that are manufactured via additive manufacturing, where the base material employed will typically have a weak sensitivity. Here, we employ friction between rough surfaces as strain-rate dependent mechanism, whose magnitude is tunable by optimizing geometry. The design along with preliminary simulation results of unit cell presented. quantify effects geometrical parameters on dissipated energy.

Finite Element Modeling of Strain Rate and Grain Size Dependency in Nanocrystalline Materials
Nanocrystalline materials show a higher strain-rate sensitivity in contrast to the conventional coarse-grained materials and a different grain size dependency. To explain these phenomenon, a finite element model is constructed that considers both grain interior and grain boundary deformation of nanocrystalline materials. The model consist of several crystalline cores with different orientations...
متن کاملTransformable topological mechanical metamaterials
Mechanical metamaterials are engineered materials whose structures give them novel mechanical properties, including negative Poisson's ratios, negative compressibilities and phononic bandgaps. Of particular interest are systems near the point of mechanical instability, which recently have been shown to distribute force and motion in robust ways determined by a nontrivial topological state. Here...
متن کاملProgrammable mechanical metamaterials.
We create mechanical metamaterials whose response to uniaxial compression can be programmed by lateral confinement, allowing monotonic, nonmonotonic, and hysteretic behavior. These functionalities arise from a broken rotational symmetry which causes highly nonlinear coupling of deformations along the two primary axes of these metamaterials. We introduce a soft mechanism model which captures the...
متن کاملHierarchical Auxetic Mechanical Metamaterials
Auxetic mechanical metamaterials are engineered systems that exhibit the unusual macroscopic property of a negative Poisson's ratio due to sub-unit structure rather than chemical composition. Although their unique behaviour makes them superior to conventional materials in many practical applications, they are limited in availability. Here, we propose a new class of hierarchical auxetics based o...
متن کاملUltralight, ultrastiff mechanical metamaterials.
The mechanical properties of ordinary materials degrade substantially with reduced density because their structural elements bend under applied load. We report a class of microarchitected materials that maintain a nearly constant stiffness per unit mass density, even at ultralow density. This performance derives from a network of nearly isotropic microscale unit cells with high structural conne...
