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 ...

Mini-punch experimental device development and analysis for ductile damage identification of naval structures [PDF]
MATEC Web of ConferencesMetallic naval structures can undergo progressive damage from external incidents, affecting their ability to withstand subsequent impacts. Ductile damage is known to be sensitive to the stress state according to two scalars, the stress triaxiality ratio ...

Bending damages in galvanized ductile cast irons
Procedia Structural Integrity, 2018 Abstract Ductile cast irons (DCIs) are characterized by mechanical properties close to low and medium carbon steels. Carbon atoms are mainly localized in graphite nodules, which are dispersed in a metallic matrix. The microstructure of metallic matrix can be ferritic, austenitic, pearlitic, martensitic or their mix, depending on chemical composition ...

Modeling gradient‐enhanced anisotropic ductile damage
, 2021 Low cycle fatigue is in general associated with large plastic strains accompanied by the formation and coalescence of pores. Considering continuum damage mechanics, many local constitutive models for ductile damage can be found in the literature. These local models however, that do not involve any length scale, lead to mesh dependent results.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
