Abstract null null The greatest challenge in creating digital material twins from μCT images is the lack of a robust and versatile tool for segmenting the μCT images and post-processing the segmented volumes into a FE mesh. Here, we have used deep convolutional neural networks (DCNN) for segmenting μCT images of a multi-layer plain-woven fabric. First, a set of raw 2D image slices extracted from the gray-scale volume of a single-layer fabric was used to train a DCNN using manually annotated imag...

Abstract null null This paper investigates the superior energy-absorbing characteristics of hollow-cylindrical-joint hierarchical honeycomb composite tubes under axial quasi-static crushing. Biomimetic multi-cell tubes (BMCTs), inspired by the forewing of a beetle, were manufactured using the vacuum bag moulding method. Quasi-static compression tests were conducted to characterize the force-displacement response, the progression of failure, the crashworthiness characteristics, and the correspond...

This paper investigates size effects on the mechanical response of additively manufactured lattice structures based on a commercially available polylactic acid (PLA) polymer. Initial attention is focused on investigating geometrical effects in the mechanical properties of simple beams and cubes. Following this, a number of geometrically scaled lattice structures based on the body-centered cubic design were manufactured and tested in order to highlight size effects in their compression properties...

Abstract null null Closed-cell materials, such as plate-lattices, are attracting increasing attention as a result of their potential to achieve the theoretical upper bounds for isotropic elasticity and strain energy storage (the Hashin-Shtrikman upper bounds) (Berger et al., 2017). However, their complex meso-geometries, especially their enclosed structures, make most of additive manufacturing methods impossible to undertake, due to difficulties associated with removing the Supporting material. ...

Abstract null null Architected cellular structures based on triply periodic minimal surfaces (TPMS) have attracted significant attention due to their lightweight, superior, and controllable mechanical properties. Such lattice structures can be potential candidates for high specific energy absorption (SEA) applications. In this study, five TPMS sheet-based structures (Gyroid, Primitive, IWP, Diamond and Fisher-Koch) were designed, fabricated, and tested under quasi­-static and dynamic loading con...

ABSTRACT Structures and machines are often exposed to sudden high-amplitude vibrations that may cause local or extended structural failure. This calls for effective and reliable methodologies for vibration mitigation, one of which is the use of linear or nonlinear dynamic vibration absorbers. Current studies in this area have focused mainly on uni-directional vibration absorbers, thus limiting their applicability in practical applications where the excitation is applied in the plane. For example...
