In recent years, mechanical metamaterials have shown good mechanical properties such as
ultralightness, programmable stiffness, and tunable Poisson's ratio through clever structural …

The current contribution investigates the strain-gradient thermomechanical performance of
architected materials and structures with uniform and graded inner designs. To that scope …

In additive manufacturing, also called 3-D printing, one of widely used materials is
polylactide thermoplastic polymer (PLA) by means of the fused deposition modeling. For …

Fused deposition modeling (FDM) is a low-cost additive manufacturing method with
moderate tolerances and high design flexibility. Ample studies are being undertaken for …

Starting from a discrete model of a pantographic beam based on beam elements with 6 DOF
in 2D space, 2 translational and 1 rotational for each end node, and proposing an energy …

A new model for a one-dimensional (1D) metamaterial model is formulated based on the
couple stress theory. Different point groups of crystal will affect the mechanical couplings in …

This study investigates the influence of infill patterns and densities on crack propagation
behavior in additive manufactured parts. Through three-point bending tests, force …

In this study, a coupled transient thermomechanical finite element model is developed to
examine the laser powder bed fusion (L-PBF) process of the Inconel 718 (IN718) and Oxide …

We propose a three-dimensional macroscopic continuum model designed to predict the
remodeling phenomenon of bone tissue. In the proposed model, we focus on the evolution …

Classical homogenization approaches applied to heterogeneous materials are suitable for
the cases where a scale-separation is eminent. As the length-scale at the effective …
