Structural Integrity Analysis of Lower Core Plate in Pressurized Water Reactors Considering Stress Triaxiality

open access: yes, 2015
The study assessed structural integrity of a lower core plate, one of pressurized water reactor internals, via finite element damage analysis. The finite element damage analysis was performed considering variations of mechanical material behaviors with ...

Constitutive modeling of void-growth-based tensile ductile failures with stress triaxiality effects

open access: yes, 2014
In most metals and alloys, the evolution of voids has been generally recognized as the basic failure mechanism. Furthermore, stress triaxiality has been found to influence void growth dramatically.

Fracture Initiation in Aluminum Alloys Under Multiaxial Loading at Various Low Strain Rates

open access: yesMetals
The initiation of ductile fractures in medium-strength AW5754 and high-strength AW6082 aluminum alloys at different quasi-static strain rates and under multiaxial stress states was investigated through a series of tensile tests using various specimen ...

The Stress Triaxiality Effect under Large Plastic Deformation of a Polybutylene Terephthalate (PBT)

open access: yes, 2018
In this work, we focus on a new generation of polymer named Polybutylene terephthalate (PBT). In order to analyse and determine true behaviour of this polymer, a special experimental method was used.
