Bayesian buckling load optimisation for structures with geometric uncertainties
Tianyi Liu, Xiao Xiao, Fehmi Cirak
Optimised lightweight structures, such as shallow domes and slender towers, are prone to sudden buckling failure because geometric uncertainties/imperfections can lead to a drastic…
A non-iterative method for robustly computing the intersections between a line and a curve or surface
Xiao Xiao, Laurent Buse, Fehmi Cirak
The need to compute the intersections between a line and a high-order curve or surface arises in a large number of finite element applications. Such intersection problems are easy…
Interrogation of spline surfaces with application to isogeometric design and analysis of lattice-skin structures
Xiao Xiao, Malcolm Sabin, Fehmi Cirak
A novel surface interrogation technique is proposed to compute the intersection of curves with spline surfaces in isogeometric analysis. The intersection points are determined in o…
Isogeometric shape optimisation of shell structures using multiresolution subdivision surfaces
Kosala Bandara, Fehmi Cirak
We introduce the isogeometric shape optimisation of thin shell structures using subdivision surfaces. Both triangular Loop and quadrilateral Catmull-Clark subdivision schemes are c…
