چکیده
A Finite element analysis has been done using ANSYS, to study the static strength of an offshore tubular T-joint. The strength of T-tubular joints with circular cross section tube chord with circular cross section tube brace is investigated. To determine the joint strength of these T-joint subjected to tension, compression, in -plane bending and out-of-plane bending loading cases have been carried out. The main objective of this work is to study the effect of static strength of T-tubular joint under various loading cases by using ANSYS. In this investigation, the displacements, stresses and yield points are obtained from finite element method. Results are compared with circular chord tubes under different loading cases. Finite element ANSYS results have been validated with the experiment results. Reasonable agreement was obtained between the finite element analysis results and the experimental values for all loading cases. The difference varies between 4.104 and 7.14 percent. This is well within the experimentation error limit of 10 percent. A comparison between the results of LUSAS Finite Element Analysis and present Finite Element Analysis through ANSYS is quite exhilarating. Another comparison with existing tubular joints design formulae showed that these formulae were conservative and highly safe for the geometrical use.

Brace and chord members of a tubular joint always have a degree of geometrical imperfection due to the manufacturing, transportation and installation processes and also the action of various loads during the lifetime of the structure. However, during the analysis and design of tubular joints, geometrical imperfection is not usually taken into account. Considering the geometrical imperfection in...
متن کاملFinite Element Analysis of Different Hip Implant Designs along with Femur under Static Loading Conditions
Background: The hip joint is the largest joint after the knee, which gives stability to the whole human structure. The hip joint consists of a femoral head which articulates with the acetabulum. Due to age and wear between the joints, these joints need to be replaced with implants which can function just as a natural joint. Since the early 19th century, the hip joint arthroplasty has evolved, a...

In welded tubular joints, when the fatigue crack depth is less than 20% of chord wall thickness, the crack growing process is highly affected by weld geometry.
 Hence, T-butt solution and weld magnification factor (Mk) are applicable tools for evaluating the crack growth rate in this domain. In this research, the capability of Artificial Neural Network (ANN) for estimating the Mk of weld toe...
