Tensile strength model of bamboo srimber by 3-p-b fracture test on the basis of non-LEFM

, 2020
Bamboo scrimber is an excellent model material for systematic and fundamental material studies of unidirectional fiber composites because of their availability and easiness in sample preparations.

Automatic LEFM crack propagation method based on local Lepp-Delaunay mesh refinement [PDF]

Advances in Engineering Software, 2010
A numerical method for 2D LEFM crack propagation simulation is presented. This uses a Lepp–Delaunay based mesh refinement algorithm for triangular meshes which allows both the generation of the initial mesh and the local modification of the current ...

LEFM Analysis and Service Simulation Testing of a Welded Frame Structure

Steel Research International, 2006
In this paper the results from fatigue analysis and testing of a welded frame are discussed. The structure contains some typical welds, which can be found on a frame to a wheel loader. The test was carried out with a service load spectrum with an overall

Investigation on Stress and Strain Singularity in LEFM

Key Engineering Materials, 2006
Stress and strain singularity at crack-tip is the characteristic of Linear Elastic Fracture Mechanics (LEFM). However, the stress, strain and strain energy at crack-tip may be infinite promoting conflicts with linear elastic hypothesis. It is indicated that the geometrical nonlinear near the crack-tip should not be neglected for linear elastic ...

Creep Crack Growth Under LEFM Conditions

Journal of Engineering Materials and Technology, 1980
The paper presents an outline model for creep crack growth under LEFM conditions. The incremental nature of the crack propagation process is taken into account, and a theoretical analysis shows that the relation between crack tip stress intensification and crack growth rate is not unique.

Limits to the applicability of LEFM in notch fatigue

Engineering Fracture Mechanics, 1984
Abstract A comparison is made between elastic-plastic, and linear-elastic, fracture mechanics parameters, for notch fatigue problems. It is shown that in high-strength aluminium alloy 2024-T351, at normal working stress levels, the errors involved in using LEFM for any crack detectable during non-destructive testing, is likely to be small.

Threshold and LEFM

2003
Figure 1 shows crack arrest data for a aluminium alloy. What is the minimum crack size above which the application of LEFM is sound? The grain size of the material is 52 µm.
