Volume 10, Issue 1 , Summer and Autumn 2020, , Pages 229-244


  The present work deals with the effect of an external circumferential elliptical crack located at thickness transition on a varied stepped diameter pipe . The purpose is the application of the extended finite element method (XFEM) for the calculation of SIF at the thickness transition region of pipe ...  Read More

Volume 8, Issue 1 , Summer and Autumn 2018, , Pages 49-60


  Abstract: The solution to problem of an orthotropic long cylinder subjected to torsional loading is first obtained by means of separation valuables. The cylinder is twisted by two lateral shear tractions and the ends of the cylinder surface of the cylinder are stress-free. First, the domain under consideration ...  Read More

3. A novel modification of decouple scaled boundary finite element method in fracture mechanics problems

Mahdi Yazdani

Volume 7, Issue 2 , Winter and Spring 2018, , Pages 243-260


  In fracture mechanics and failure analysis, cracked media energy and consequently stress intensity factors (SIFs) play a crucial and significant role. Based on linear elastic fracture mechanics (LEFM), the SIFs and energy of cracked media may be estimated. This study presents the novel modification of ...  Read More

4. Prediction of forming limit curves (FLD, MSFLD and FLSD) and necking time for SS304L sheet using finite element method and ductile fracture criteria

Kamal Kolasangiani; Mahmoud Shariati; Khalil Farhangdoost

Volume 4, Issue 2 , Winter and Spring 2015, , Pages 121-132


  Forming limit curves are used as a parameter in finite element analysis to control the material's level of formability. In this research, forming limit diagram (FLD) of SS304L sheet was obtained by ABAQUSfinite element software. In practice, the experimental determination of a forming limit curve is ...  Read More

5. Fracture mechanics-based life prediction of a riveted lap joint

A. R. Shahani; H. Moayeri Kashani

Volume 4, Issue 1 , Summer and Autumn 2014, , Pages 1-17


  In this paper, three-dimensional modeling of the fatigue crack growth profiles was performed in a simple riveted lap joint. Simulation results showed that mode I was dominated on the one side of the plates and the crack straightly grew on this side, while the other side of the plates was in a mixed-mode ...  Read More

6. A numerical and experimental study on buckling and post-buckling of cracked plates under axial compression load

M. Shariati; A. M. Majd Sabeti; H. Gharooni

Volume 4, Issue 1 , Summer and Autumn 2014, , Pages 43-54


  Existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. Therefore, it must be considered in stress analysis and designing and loading of such structures. In this ...  Read More

7. Finite element prediction of ductile fracture in automotive panel forming: comparison between FLD and lemaitre damage models
Volume 1, Issue 1 , Summer and Autumn 2011, , Pages 37-44


  In sheet metal forming processes with complex strain paths, a part is subjected to large plastic deformation. This severe plastic deformation leads to high plastic strain localization zones and subsequent accumulation of those strains. Then internal and superficial micro-defects and in other words ductile ...  Read More
