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…
Level set-based inverse homogenisation of three-dimensional piezoelectric materials
Zachary J. Wegert, Anthony P. Roberts, Vivien J. Challis
In this paper we use memory-distributed level set-based topology optimisation to design three-dimensional periodic piezoelectric materials with enhanced properties. We compare and…
GridapTopOpt.jl: A scalable Julia toolbox for level set-based topology optimisation
Zachary J. Wegert, Jordi Manyer, Connor Mallon +2
In this paper we present GridapTopOpt, an extendable framework for level set-based topology optimisation that can be readily distributed across a personal computer or high-performa…
