Mathematical model of elastic crack interaction and two-dimensional finite element analysis based on griffith energy release rate
(Universiti Malaysia Perlis (UniMAP), 2013-03-26)
Stress shielding interaction effect of two parallel edge cracks in finite body under
uniaxial loading is analysed using developed finite element (FE) analysis program. In present study,
the stress shielding interaction ...
Stress intensity factors under combined bending and torsion moments
(Zhejiang University and Springer-Verlag Berlin Heidelberg, 2012-01)
This paper discusses stress intensity factor (SIF) calculations for surface cracks in round bars subjected to combined torsion and bending loadings. Different crack aspect ratios, a/b, ranging from 0.0 to 1.2 and relative ...
Mode I stress intensity factor for parallel cracks in finite body
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper presents a numerical approach to study a
multiple crack problem in metallic finite body. The aim
is to evaluate the stress intensity factor (SIF) of
dimensionless cracks interaction based on equal and
parallel ...
Recent fatigue reliability assessment of welded joint
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
Over recent years, the implementation of reliability
based analysis in fracture and fatigue assessment of
welded joint has escalated. The accuracy of the
reliability based analysis and evaluation are demanded
by the ...
J-integral analysis of surface cracks in round bars under bending moments
(Trans Tech Publications, 2011-04)
Stress and probabilistic study of the lumbar vertebra under compression loading
(Trans Tech Publications, 2011-03)
The objectives of this study were to determine the stress concentration of the lumbar vertebra and the probability of failure associated with finite element method. The lumbar vertebra model was constructed in SolidWorks ...
Computation of mixed mode stress intensity factor for parallel edge cracks
(Trans Tech Publications, 2011-03)
This paper presents the extensions of newly developed finite element (FE) formulation to evaluate fracture behavior of parallel edge cracks problems. The numerical formulation used Barsoum singular finite elements to compute ...
J-integral analysis of surface cracks in round bars under tension loadings
(Trans Tech Publications, 2011-04)
This paper presents a non-linear numerical investigation of surface cracks in round bars under tension stresses by using ANSYS finite element analysis (FEA). Due to the symmetrical analysis, only quarter finite element ...
J-integral evaluation in two dimensional interacting cracks
(Trans Tech Publications, 2011)
This paper investigates crack interaction of multiple edge cracks in elastic solid finite body under pure Mode I loading. The cracks are located in parallel to another in 2D plate model. The stress intensity factors (SIFs) ...
Fatigue failure analysis using the theory of critical distance
(Malaysian Association for Computational Mechanics (MACM) and Far East and Oceanic Fracture Society (FEOFS), 2010-06-07)
This paper explores the initial potential of theory of critical distance (TCD) which offers essential fatigue failure prediction in engineering components. The intention is to find the most appropriate TCD approach for a ...
