Two-dimensional fracture analysis of FGM under mechanical loading

Journal of Materials and Engineering Structures, 2020
This paper extends the concept to isotropic functionally graded materials and addresses fracture problems under mechanical loading. The mode-I and mixed mode stress intensity factors (SIFs) are determinate by combination between the finite element method

Stress-intensity factor equations for cracks in three-dimensional finite bodies subjected to tension and bending loads [PDF]

Stress intensity factor equations are presented for an embedded elliptical crack, a semielliptical surface crack, a quarter elliptical corner crack, a semielliptical surface crack along the bore of a circular hole, and a quarter elliptical corner crack ...

The crack problem in a specially orthotropic shell with double curvature [PDF]

The crack problem of a shallow shell with two nonzero curvatures is considered. It is assumed that the crack lies in one of the principal planes of curvature and the shell is under Mode I loading condition.

A failsafe analysis using NASTRAN's piecewise linear analysis and a nine node linear crack element [PDF]

, 1975
A two-dimensional crack element was implemented into NASTRAN as a user dummy element and used to study failsafe characteristics of the C5A fuselage. The element is formulated from Reitsner's functional requiring that it satisfy compatability with the ...

Effect of crack position and loading conditions on SIF in SiC particles reinforced Al composite

Fracture and Structural Integrity, 2019
In this paper the effect of reinforcement crack position and loading conditions (in mode I) on the stress intensity factors of the Al/SiCp metal matrix composite was examined using a finite element method.

COMPLEX VARIABLE FUNCTION SOLUTIONS OF MIXED-MODE STRESS INTENSITY FACTORS FOR TWO CRACKS OF ARBITRARY LENGTH EMANATING FROM AN ELLIPTICAL HOLE

Jixie qiangdu, 2019
In order to calculate the stress intensity factors of two-dimensional cracks emanating from elliptical hole, a solution method for stress intensity factor based on Muskhelishvili complex function theory and truncated conformal mapping approach is ...

Stress intensity factors in a reinforced thick-walled cylinder [PDF]

An elastic thick-walled cylinder containing a radial crack is considered. It is assumed that the cylinder is reinforced by an elastic membrane on its inner surface. The model is intended to simulate pressure vessels with cladding.

Improved stress-intensity factors for semi-elliptical surface cracks in finite-thickness plates [PDF]

Stress-intensity factors for shallow and deep semi-elliptical surface cracks in plates subjected to tension are presented. To verify the accuracy of the three-dimensional finite-element models employed, convergence was studied by varying the number of ...
