Predicting the critical buckling loads of functionally graded material (FGM) plates using an analytical method requires solving complex equations with various modes of deformation to determine the minimum loads. The approach is too complex for application in engineering practice. In this paper, a data-driven model using the artificial neural network (ANN) is proposed for the critical buckling load of FGM plates, as an alternative tool for practicing engineers. A database is first developed for r...

Abstract Establishing an accurate model to predict burst pressure is desired, which has been developed for decades. Although various models have been developed, errors unavoidably appear in the prediction of burst pressures because of the uncertainty in both input variables and nonlinear relationship of such variables to the burst pressure. Consequently, machine learning models, which is a data-driven approach, are potential alternatives. In this paper, various machine learning models such as Ra...

Abstract The municipal water distribution systems across the world include a significant amount of cast-iron pipes. Many of the buried cast-iron pipes are over fifty years old and require rehabilitation. Municipalities decide on a rehabilitation solution between the replacement and re-use of the existing pipes based on the remaining strengths of the pipes. Fracture mechanics has appeared as the most viable tool for remaining strength assessment of the deteriorating pipes. However, a method of as...

The mechanical damages created on buried pipelines by any external activities are important consideration to assess the structural integrity of pipelines. The damages could be in the form of corrosion, dent, crack, gouge or any combination of these. A dent is a permanent inward plastic deformation in the pipe wall. The dents may not immediately cause failure of the pipe. However, it can reduce the pipe’s structural capacity and cause rupture or leak in the long run. The current researches focus ...
