Influence of matrix toughness and interfacial strength on the toughness of epoxy composites with ductile steel fabric reinforcement [PDF]
, 2015 In the last decades, several studies have been performed on polymers reinforced with steel cords or wires. However, the diameter of these steel reinforcements was still quite large (200 micron and more).

From Brittle to Ductile Fracture in Disordered Materials [PDF]
, 2010 We introduce a lattice model able to describe damage and yielding in heterogeneous materials ranging from brittle to ductile ones. Ductile fracture surfaces, obtained when the system breaks once the strain is completely localized, are shown to correspond

Strength and Ductility of Damaged Tempcore Rebars
Procedia Engineering, 2015 AbstractThe Tempcore rebars behaviour results from the interaction of the three layers that compose them, with different initial stresses. Therefore,their mechanical properties study is important for the understanding of the rebar overall behaviour. In this paper it is presentedand discussed the results of hardness, strength and ductility obtained in ...

Implementation of the Quasi-Brittle Damage Model for 2024 Aluminum Alloy under Periodic Loading [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2019 Damage mechanics is one of the most important parts of mechanical engineering that determines the time life for different mechanical elements. The most various models that have been provided so far in damage mechanics, are related to ductile or brittle ...

The Evaluation of Varying Ductile Fracture Criteria for 3Cr20Ni10W2 Austenitic Heat-Resistant Alloy
Advances in Mechanical Engineering, 2013 Most bulk metal forming processes may be limited by ductile fracture, such as an internal or surface fracture developing in the workpiece. Finding a way to evaluate the ductile fracture criteria (DFC) and identify the relationships between damage ...
