Comparative study between crack tip opening displacement techniques by statistical analysis [PDF]

Tecnologia em Metalurgia, Materiais e Mineração, 2021
Standardized tests may not always achieve all their analytical objectives. Particularly to structural integrity, where a reproduction of the practical occurrences of the industry is desired, new techniques are being developed. Therefore, this work aims at evaluating fracture toughness in tensile armour through four measurement methodologies (standard ...

Mode I Fracture Toughness of Tangential Moso Bamboo

BioResources, 2014
This paper discusses moso bamboo (Phyllostachys pubescens) with initial crack formation by a three-point bending (SENB) method. The corrected indentation load-displacement curve (ISO 13586-2000) and the crack opening displacement in determining the crack

Effect of Thickness on Fatigue Crack Propagation in Injection Molded Short Carbon Fiber Reinforced Plastics

MATEC Web of Conferences, 2018
The influence of plate thickness on the fatigue crack propagation behavior was studied by using center-notched specimens which were cut from injection-molded plates of short carbon-fiber reinforced polyphenylene sulfide (PPS) at two fiber angles relative

Modelling localised fracture of reinforced concrete structures [PDF]

, 2016
This paper presents a robust finite element procedure for simulating the localised fracture of reinforced concrete members. In this new model the concrete member is modelled as an assembly of plain concrete, reinforcing steel bar and bond-link elements ...

Experimental investigation of mixed-mode-I/II fracture in polymer mortars using digital image correlation method

Latin American Journal of Solids and Structures
The purpose of this work is to investigate experimentally the effects of mixed-mode I/II loading on the fracture behavior of polymer mortars. Three point bend beam specimens with offcenter notch were used in plane-strain fracture toughness tests.

Evolution of residual stress at a fatigue crack tip and its influence on crack tip shielding and plasticity

Journal of Materials Research and Technology
The evolution of residual stresses (RS) at a crack tip and associated changes in crack shielding effects during fatigue crack growth (FCG) has a first order effect on the fatigue life of welded joints.

A new displacement-based approach to calculate stress intensity factors with the boundary element method [PDF]

, 2015
The analysis of cracked brittle mechanical components considering linear elastic fracture mechanics is usually reduced to the evaluation of stress intensity factors (SIFs).
