With illustrative examples we have shown that the stress field, at the boundary of a drilled stress releasing hole, can be significantly improved. To a large extent the one parameter superelliptic shape is able to return a field of constant tangential stress along the boundary. This will ...
shape of a hole, such as a grave, dug in the ground, an inflatable bag is lowered into the hole and then inflated to a low pressure so as substantially to fill the hole, thus maintaining the sides of the hole against subsidence and also largely preventing water seeping into the hole. ...

Effect of Internal Coolant Crossflow on the Effectiveness of Shaped Film-Cooling Holes Film-cooling was the subject of numerous studies during the past decades. However, the effect of flow conditions on the entry side of the film-cooling hole... M Gritsch,A Schulz,S Wittig - 《Journal of Tu...
At the head of the bed lay more petals placed into the shape of a large heart. Escher Walcott, Peoplemag, 30 July 2023 So the shape of both the light source and the hole do indeed matter. Rhett Allain, WIRED, 5 Apr. 2024 Santamaria sketched the mural and traced the shapes for ...

By analyzing the vibration modes of the unit cell of the phononic crystal, we find the origin of the lower frequency band is due to the locally resonant mechanism. Moreover, the impacts of the size of the fractal hole on the band structure are studied. (C) 2013 Elsevier B.V. All ...

shape of the droplet residues can be controlled both by restricting evaporation and by combining high and low boiling point solvents which modify particle flows and produce a range of droplet residues varying from a concave "doughnut" shape, sometimes with a central hole, to a convex dome shape...
