Determining and predicting the seakeeping performance of ships based on jerk in the ship motions

The comfort assessment of ships is based on several criteria. There are for example criteria for motions, noise and vibrations. The criteria for motions are nowadays often defined as comfort limits on the accelerations in the ship motions. However, from other industries it followed that the rate of change of the accelerations, the jerk, can also...

Tungsten Recrystallization Behavior Under Steady and Transient Hydrogen Plasma Loading

Because of its extraordinary material properties, like its high melting point and thermal stress resistance, low erosion and swelling rate, and high radiation damage resistance, highly deformed pure tungsten has been chosen as the plasma facing surface material for the ITER reactor divertor. The study of tungsten’s recrystallization behavior and...

Dislocation networks in precipitation hardened aluminium alloys during plastic deformation: The effects of dislocations on the anelastic behaviour and the evolution of dislocation networks in an AA7075 aluminium alloy.

The effects of precipitates in the microstructure of an AA7075 aluminium alloy on: the dislocation behaviour, dislocation structure and dislocation structure evolution during plastic deformation were investigated using the physical yield criterion model by van Liempt and Sietsma. The model was in fact applied for the first time to aluminium and...

Unraveling the Role of Carbon on the Strengthening Mechanisms of Low Mn-Si Martensitic Steels

The role of carbon in the strengthening mechanisms of martensitic steels has been studied for decades. However, uncertainties still exist regarding how the distribution of carbon to various locations inside martensite contributes to the development of its observed microstructure and high strength. The strengthening mechanisms depend on carbon...
