To respond to the increasing need for bone repair strategies, various types of biomaterials
have been developed. Among those, calcium phosphate (CaP) ceramics are promising …

Polymeric foams have good capacity of absorbing energy in compression but are brittle in
tension. Linear elastic fracture mechanics is successfully applied to assess the integrity of …

The only engineering materials with both high strength and toughness, and with densities
less than 1000 kg m− 3, are natural materials (woods) and some plastics. Cellular structures …

The systemic comparison between sheet-based triply minimal surfaces (TPMS), strut-based
ordered lattice topologies and plate-based lattice topologies offer insights into designs for …

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 …

This study focuses on the fracture properties of strut-based lattice materials following a
global energy-based approach. We focus on two typical isotropic lattices, the regular …

Prior analytical and numerical studies have shown that the triangular lattice is one of the
stiffest, strongest and toughest geometries of 2D lattices. However, there has been little …

Many naturally occurring materials, such as wood and bone, have intricate porous micro-
structures and high stiffness and toughness to density ratios. Here, the influence of pores in …

We consider the controlled non-localized brittle fracture of a periodic beam-lattice subjected
to tensile loading. The specific lattice architecture ensures overstress of a periodic group of …

Polyurethane (PUR) foam materials are widely used as cores in sandwich composites, for
packing and cushioning. They are made of interconnected networks of solid struts and cell …
