Experimental investigation of effects of residual stresses on fatigue crack growth in pipelines with allowance for the scale effects

In offshore industry, subsea pipelines are used for transporting oil and gas from wells to remote platforms and from platforms to nearby shores. A microscopic flaw in pipeline during installation and operation will grow normal to the principal stress if the threshold value of fatigue stress range is exceeded. In case, these microscopic flaws...

Structural Study and Parametric Analysis on Fatigue Damage of a Composite Rotor Blade

Fatigue damage calculations are conducted as state-of-art design process for wind turbines. Fatigue analysis is performed on spar caps and trailing edge tape (UD material) considering uni-axial stress state. The main objective of the research project is to analyze the effect of various parameters like yaw errors, wind turbine design load cases...
