Fatigue Safety Factors for Dynamic Power Cables: A reliability based approach

In contrast to traditional power cables for bottom-founded offshore wind turbines, power cables for floating wind turbines penetrate the water column and are exposed to cyclic loading. Due to the dynamic nature of the cable loading, the cables are prone to fatigue failure. Since the evaluation of the fatigue life of complex structures, like...

Finding the strength of glass: A mechanical and fractographic research of glass' biaxial strength for structural purposes

Over the years, glass has been increasingly used as a structural building material. Structural calculations on glass are conservative because the strength is quite uncertain. Weibull plots of the strength of glass can range from 20 MPa to 150 MPa. This is caused by flaws, which are not visibile to the human eye and therefore it is difficult to...

Asphalt Mixture Fatigue Testing: Influence of Test Type and Specimen Size

Fatigue characterization of an asphalt mixture is commonly estimated by laboratory fatigue tests. Based on the classical fatigue analysis, fatigue lives obtained from different test devices are not comparable even when they are performed at the same test conditions. It is believed that there are two main reasons causing the difference in fatigue...

Rationalisation of safety and serviceability factors in structural codes

Suitable methods for the determination of partial safety factors were investigated. The safety formats adopted in a number of national codes and standards are reviewed. Safety provisions currently used in the design of aircraft, ships and structures for nuclear energy plants are discussed. A study has been made of various constraints which...
