This paper presents the Virtual-Trim, a novel method for the geometric modeling of heterogeneous strut-based lattice structures that is both efficient and robust. Virtual-Trim begins with user-defined wireframe models and geometric information to create STL (STereoLithography) models ready...
Lightweight parts consisting of lattice structures can be easily fabricated by additive manufacturing and are becoming potential choices for aerospace and other applications. Lattice structures can be strut-based, surface-based, or planar-based. The present work studied and compared the flexural load-be...

The formation of shear band in metallic lattice structures under compression prompts an unstable stress鈥搒train curve, resulting in a significant reduction in the energy absorption capacity. The development and formation of shear band need to be clarified, and versatile approaches to suppress the ...
A new lattice structure is presented by adding the strut to the surface-based unit cell which has a higher energy absorption capacity than the lattice structures with surface-based unit cell. First, the high energy absorption capacity of surface-based lattice structures was evaluated by adding the...
It is observed that by combining different lattice structures in a hybrid approach, a decrease in the anisotropic behavior is obtained, and an overall enhancement of the mechanical properties is achieved. The numerical results show rather good agreement with the experimental findings. The current ...
The advent of additive manufacturing (AM) has enabled the prototyping of periodic and non-periodic metamaterials (a.k.a. lattice or cellular structures) that could be deployed in a variety of engineering applications where certain combinations of performance features are desirable. For example, these...
Strut-based lattice structures offer a potential solution to this problem. They are made of a network of struts that provide support while allowing for more bone growth. This review paper explores the development of titanium strut-based lattice structures, made utilizing additive manufacturing ...
