Shape calculus and automatic differentiation for multi-phase level-set topology optimisation with unfitted finite elements
Zachary J. Wegert, Martin Berggren, Vivien J. Challis
We present shape calculus techniques and a scalable automatic shape differentiation framework for multi-phase topology optimisation on unfitted discretisations defined by several l…
Topology optimisation and simulated state reconstruction for self-sensing piezoresistive grippers
Connor N Mallon, Zachary J Wegert, Anthony P Roberts +3
We consider the computational design of a self-sensing robotic gripper that has the potential to reduce reliance on traditional external sensors. We computationally investigate the…
A discontinuous finite element method for the hydroelastic analysis of submerged structures
Zachary J. Wegert, Oriol Colomés, Michael H. Meylan +2
This paper develops a finite element method for wave-structure interaction problems arising in the hydroelastic modelling of submerged elastic plates. The approach is formulated fo…
Wave energy conversion by floating and submerged piezoelectric bimorph plates
Zachary J. Wegert, Ben Wilks, Ngamta Thamwattana +3
Gaining insight into the interaction between flexible piezoelectric structures and ocean waves can inform the development of compact, high-efficiency wave-energy converters that ha…
Water wave scattering by a surface-mounted rectangular anisotropic elastic plate
Ben Wilks, Michael H. Meylan, Zachary J. Wegert +2
This paper considers the problem of water wave scattering by a rectangular anisotropic elastic plate mounted on the ocean surface, with either free, clamped or simply-supported edg…
Level-set topology optimisation with unfitted finite elements and automatic shape differentiation
Zachary J. Wegert, Jordi Manyer, Connor Mallon +2
In this paper we develop automatic shape differentiation techniques for unfitted discretisations and link these to recent advances in shape calculus for unfitted methods. We extend…
