Numerical Study about the Influence of Superimposed Hydrostatic Pressure on Shear Damage Mechanism in Sheet Metals

open access: yesMetals, 2021
It is generally accepted that the superimposed hydrostatic pressure increases fracture strain in sheet metal and mode of fracture changes with applying pressure.

Parameter identification of a mechanical ductile damage using Artificial Neural Networks in sheet metal forming. [PDF]

open access: yes, 2013
In this paper, we report on the developed and used of finite element methods, have been developed and used for sheet forming simulations since the 1970s, and have immensely contributed to ensure the success of concurrent design in the manufacturing ...

Riboflavin: The Health Benefits of a Forgotten Natural Vitamin [PDF]

open access: yes, 2020
Riboflavin (RF) is a water-soluble member of the B-vitamin family. Sufficient dietary and supplemental RF intake appears to have a protective effect on various medical conditions such as sepsis, ischemia etc., while it also contributes to the reduction ...

Ductile damage modelling with locking‐free regularised GTN model

open access: yesInternational Journal for Numerical Methods in Engineering, 2018
SummaryThe major goal of this work is to develop a robust modelling strategy for the simulation of ductile damage development including crack initiation and subsequent propagation. For that purpose, a Gurson‐type model is used. This model class, as many other damage models, leads to significant material softening and must be used within a large ...

Simulation of edge cracking using shear GTN damage model during hot plate rolling of magnesium alloys

open access: yesIOP Conference Series: Materials Science and Engineering, 2022
Edge cracks are a more prominent problem during the rolling process of magnesium alloy sheets. The hexagonal structure of magnesium alloys and the product defects caused by the second phase impurities mixed in the sheets are the main causes of edge ...

Application of Gurson-Tvergaard-Needleman constitutive model to the tensile behavior of reinforcing bars with corrosion pits. [PDF]

open access: yesPLoS ONE, 2013
Based on meso-damage mechanics and finite element analysis, the aim of this paper is to describe the feasibility of the Gurson-Tvergaard-Needleman (GTN) constitutive model in describing the tensile behavior of corroded reinforcing bars.
