An Integrated Machine Learning and Finite Element Analysis Framework, Applied to Composite Substructures including Damage

Engineering fields such as aerospace rely heavily on the Finite Element Method (FEM) as a modelling tool. In combination with the scale and complexity of the structures typically involved here, computational cost remains a traditional issue. To perform FEM analyses of such structures efficiently nonetheless, engineers rely on techniques such as...

Robust Experimental Dynamic Substructuring: Enhanced quality indicators & application of SEMM to an industrial case

A popular strategy in structural dynamic modeling is breaking the structure down into separable, manageable substructures. By doing so, one can choose the most efficient way of modeling the substructures, before synthesizing the full system model. This method is known as Dynamic Substructuring (DS). One method of DS, is Frequency Based...

Vibration Analysis of a Steering System using Frequency Based Substructuring

The design of a modern vehicle must fulfill high standards regarding safety and ride comfort as well as vehicle dynamics. This is of particular importance for front suspension and steering system as the latter is the only tactile connection between road and driver. The vibration feedback from the tires to the steering wheel delivers both useful...

Analysis of Shell Deformations of Offshore Wind Turbine Monopile Foundations

A significant reduction in the levelized cost of electricity is necessary for offshore wind farms to become a competitive energy source. Amongst other methods, overall project cost reduction can be achieved by optimized support structure design. An upcoming trend is the use of `XL monopiles', which provide a cost effective foundation solution...

Impulse Based Substructuring Unravelled; Simulation and Coupling of Structural Dynamics in the Time Domain

One way of deriving the dynamics of a structure, is by combining the dynamics of its substructures. This concept is named ’Dynamic Substructuring’ and it allows us to cope with the increasing complexity of models by dividing them into substructures and deriving their structural dynamics independently. This allows an improvement in computational...
