  • Finite element analysis of buried continuous pipeline subjected to fault motion

    Pipeline generally extends over long distances traversing through wide variety of different soils, geological conditions and regions with different seismicity. Most analytical models developed in the past for pipeline fault crossing are of limited usage as models developed were useful only for strike slip fault. Incorporating the large geometric changes in analytical study is a tricky task; ...

  • Finite element parametric study of reinforced concrete skew slabs

    The numerical formulation and a finite element computer program were developed for the non–linear analysis of reinforced concrete skew slabs. It is important to ensure that the proposed model should perform well in a variety of situations. Before comparing the overall performance of the numerical model with the experimental results, a parametric study was undertaken to observe the influence of ...

  • Predicting the head-leakage slope of cracks in pipes subject to elastic deformations

    Pressure has a major impact on the rate of leakage from leak openings in pipes and studies have shown that the leakage exponents in networks can be substantially larger than the theoretical orifice exponent of 0.5. The most important reason for this behaviour is that leak areas are not fixed, but increase as a function of pressure. In this study, finite element analysis was used to investigate ...

  • Finite element analysis of slip damping in riveted built–up beams

    Damping in built–up structures is produced by the energy dissipation due to micro–slip along the frictional interfaces. A finite element model of the linear elastic system has been formulated using the Euler–Bernoulli beam theory to investigate the damping phenomena in riveted connections. The discrete element system having two degrees of freedom per node representing ν and ∂v/∂x has been used ...

  • Case study of an evaluation of a Stacker Boom Luffing Pulley by Irwin's model and under BS 7910 guidance

    A case study on evaluation of a heavy–duty Stacker Boom Luffing Pulley was presented. Irwin's fracture toughness method and the British Standard were used to help in the decision–making process. Using inspection, discontinuities were found at the first look in the cylinder cross–section at the region of welding of the cylinder ends. A more detailed analysis was conducted by ultrasonic mapping, ...

  • Impact of inverter on losses and thermal characteristics of induction motors

    This paper investigated the losses and thermal characteristics of induction motors operated from pulse width-modulated (PWM) voltage supply in comparison to that operated from sinusoidal voltage supply. It was concluded that due to the abundant harmonics in the PWM waveforms, significant losses are induced in the motor by the inverter supply. The temperature ascends correspondingly. Switching ...
