Shock waves and shock-shock interaction are typical phenomena in supersonic or hypersonic flows that have significant impacts on aerodynamic performance. To obtain a comprehensive understanding of the mechanism shock wave interaction, detection (SWD) methods required. However, it is often challenging for most current SWD to identify relationship between (also known as topology). address this is...

The present work is devoted to the extension of non-gradient approach, namely Proportional Topology Optimization (PTO), for compliance minimization three-dimensional (3D) structures. Two schemes material interpolation within framework solid isotropic with penalization (SIMP), i.e. power function and logistic are analyzed. Through a comparative study, efficiency logistic-type scheme highlighted....

Recent studies on viscous streaming flows in two dimensions have elucidated the impact of body curvature variations resulting flow topology and dynamics, with opportunities for microfluidic applications. Following that, we present here a three-dimensional characterization as function changes geometry topology, starting from well-known case sphere to progressively arrive at toroidal shapes. We l...

In this paper, topology optimization is utilized for damage detection in three dimensional elasticity problems. In addition, two mode expansion techniques are used to derive unknown modal data from measured data identified by installed sensors. Damages in the model are assumed as reduction of mass and stiffness in the discretized finite elements. The Solid Isotropic Material with Penalization (...

3D printing services are appearing, allowing consumers or businesses to order custom parts for delivery within a quoted lead-time, regardless of design specification. The manufacturer’s problem is to ensure that customers receive their goods on time, while capacity costs (including overtime costs) are kept low. We introduce a performance measure called the service rate, analogous to the fill ra...
