Abstract: This paper introduces a topology optimization approach based on the virtual element method (VEM), incorporating uncertainties. The objective of this optimization process is to design an optimal material layout for problems ...

Abstract: This paper presents an effective and low-cost method for fabricating spherical and aspheric microlenses based on excimer laser LIGA-like processes. It is based on a newly developed excimer laser ...

Abstract: Pipeline vibration induced by fluid flow can cause pipeline fatigue damage, which seriously endangers the safety of the operation. This paper aims to clarify the dynamic variation law of pipeline vibration induced by ...

Abstract: The recent advancements in theories and numerical methods of engineering optimization have paved the way for the widespread application of computational techniques in architectural and structural design, as well as software ...

Abstract: This paper presents a theoretical model for the radiative properties of fiber composites fabricated of spatially oriented fiber strands that contain closely spaced fibers in the Mie scattering ...

Abstract: This study constructs a new phononic crystal acoustic wave device that adopts a graphenelike structure and is composed of piezoelectric zinc oxide (ZnO) material. We employed the finiteelement method to determine periodic ...

Abstract: A continuum bubbly mixture model coupled to the Rayleigh-Plesset equation for the bubble dynamics is employed to study one-dimensional steady bubbly cavitating flows through a converging-diverging ...

Abstract: The nonlinear dynamics of a spherical bubble cloud with nuclei size distribution are studied numerically. The spectrum of nuclei is assumed uniform initially. The simulations employ a nonlinear ...

Abstract: Tests were carried out on shear walls with diagonal or transverse (horizontal) lumber sheathing. A total of 16 full-scale shear walls were tested to investigate the effects of hold-downs, vertical load, and width of lumber ...
