In this paper, a method based on a combination of an optimization of directions of orthotropy, along with topology optimization, is applied to continuum orthotropic solids with the objective of minimizing their compliance. The spatial discretization algorithm is the so called Meshless Local Petrov-Galerkin (MLPG) “mixed collocation” method for the design domain, and the material-orthotropy orie...

Topology optimization is concerned with the identification of optimal shapes deformable bodies respect to given target functionals. The focus this paper on a topology problem for time-evolving elastoplastic medium under kinematic hardening. We adopt phase-field approach and argue by subsequent approximations, first discretizing time then regularizing flow rule. Existence proved both at time-dis...

Due to developments in additive manufacturing, the production of piezoelectric materials with complex geometries is becoming viable and enabling the manufacturing of thicker harvesters. Therefore, in this study a piezoelectric harvesting device is modelled as a bimorph cantilever beam with a series connection and an intermediate metallic substrate using the plain strain hypothesis. On the other...
