Temperature is one of the main factors affecting the properties of polyurethane foams, and
there are large differences in the mechanical properties of polyurethane foams at different …

This paper discusses methods of using biomass from the agriculture, forestry, food and
aquaculture industries as potential raw materials for bio-polyols and as fillers in the …

This paper investigates the compression-compression fatigue behaviour of polyurethane
rigid (PUR) foams of three relative densities (RDs): 0.0854, 0.1239 and 0.2564 respectively …

This paper investigates the collapse diagrams (energy-absorption and efficiency diagrams)
under dynamic compression tests (drop tests) with an impact loading speed of 3.09 m/s …

The research presented in this paper is an effort to better understand the fracture toughness
of closed-cell rigid polyurethane (PUR) foams under different loading and temperature …

In this research, the mechanical behavior of closed-cell aluminum (Al)-alloy foams was
investigated at different temperatures in the range of 25-450° C. The main mechanical …

The management of by-products and waste from agriculture and the agri-food industry is a
challenge for the plastics industry. Flexible polyurethane foams (EPPUR) containing ground …

This paper investigates the failure strain as a dependence of the stress triaxiality and the
Lode angle parameter for polyurethane rigid foams (PUR) of two densities (100 and 300 …

A cellular structure is made up by an interconnected network of beams or plates which forms
the edges and faces of cells. This paper proposes three different micromechanical models to …

Porous materials have significant advantages, such as their light weight and good specific
energy absorption. This paper presents the designs of two ordered Voronoi structures, a …
