Oxide ceramics could be attractive high-temperature construction materials for critical structural parts in molten salt thermal energy storage systems due to their excellent corrosion resistance and good mechanical properties. The 3D-printing technology allows the production of ceramic components with highly complex geometries, therefore extends applications. In this work, 3D-printed ZrO2 Al2O3...

A flexural model of four-point bending fatigue that has been experimentally validated for human cortical bone under load control was used to determine how load and displacement control testing affects the fatigue behavior of human cortical bone in three-point and symmetric four-point bending. Under load control, it was predicted that three-point bending produced no significant differences in fa...

Composite materials are used in a wide range of applications, but due to their inherent nature heterogeneity, particularly for thermoset-based polymer composites, recycling is problem, and life cycle management remains one, too. This study applies circular economy approach the problem excess waste glass fibre (GF) composites seeks solution by testing methodology thermal GF combining different t...

We study the crackling noise emerging during single crack propagation in a specimen under three-point bending conditions. Computer simulations are carried out in the framework of a discrete element model where the specimen is discretized in terms of convex polygons and cohesive elements are represented by beams. Computer simulations revealed that fracture proceeds in bursts whose size and waiti...
