NURBS as basis functions for analysis have proven to be very efficient … Web2 dagen geleden · In this work, a linear Kirchhoff-Love shell formulation in the framework of scaled boundary isogeometric analysis is presented that aims to provide a simple approach to trimming for NURBS-based shell analysis. To obtain a global C1-regular test function space for the shell discretization, an inter-patch coupling is applied with adjusted basis …
WebNow we will have a look at the implementation in kirchhoff-Love_example.cpp. The file starts with a large amount of classes being defined. These classes all inherit from the class _expr which means that they are G+Smo expressions. Without going into detail for the implementations of all the classes, the following functions match with the ...

Web2 mrt. 2024 · Abstract. A new moving Kirchhoff–Love plate element is developed in this work to accurately and efficiently calculate the dynamic response of vehicle–pavement interaction. Since the vehicle can only affect a small region nearby, the wide pavement is reduced to a small reduced plate area around the vehicle. The vehicle loads moving …
