Effective Notch Stress Concept Investigations for Mode-III Loading & Response Conditions

Fatigue strength is typically a governing limit state for marine structures. Predicting an accurate fatigue lifetime is important for structures (e.g. wind turbines) that are supposed to be out at sea for decades. It is valuable for all type of structures that encounter stochastic sea loadings to optimise the design so that fatigue failure is...

Major axis steel joint under torsion: Stiffness and strength characterization

Torsional effects in joints need to be investigated in order to get a complete model of the joint and also to assess the real boundary conditions for the lateral torsional effects in the beams of structural frames. Phenomena such as: torsion, warping, lateral buckling, etc. are usually analysed assuming simplified boundary conditions, namely...

On fictitious joints modelling of manipulator link flexibility for the HERA simulation facility pilot

The mathematical model for the dynamics of HERA must take into account structural flexibility in the slender manipulator links. For the HERA Simulation Facility Pilot, the model will contain one bending mode in each bending plane, and one torsion mode. The present document describes how this model can be simulated with rigid body simulation...
