Abstract In true triaxial compression tests, all three principal stresses are imposed independently. This allows for a more comprehensive analysis of the material's mechanical properties. The end effect in true triaxial compression tests is a crucial

Abstract We carried out uniaxial compression tests on brittle red sandstone with different heights. The test results show that the uniaxial compressive strength of rock sample increases first and then tends to be stable with the increase of the size,

This paper presents an improved subdomain model for predicting the open-circuit magnetic field of a permanent magnet synchronous linear motor (PMSLM), taking into consideration the axial array and primary end effects. The improved subdomain model inv

The causes of the size effect (SE) and loading rate effect (LR) for rocks remain unclear. Based on this, a gypsum-mixed material was used to simulate sandstone, where the dosing ratio was 7.5% river sand, 17.5% quartz, 58.3% α-high-strength gypsum,

Abstract Highly rarefied gas flows through a rough channel of finite length with small bumps appended to its surfaces are investigated, by varying the accommodation coefficient $$\alpha$$ α in Maxwell’s diffuse-specular boundary condition, the cha

Detent force is an inherent problem of permanent magnet linear synchronous machines (PMLSMs). In this paper, a mesh-level design methodology is proposed to minimize the detent force on PMLSMs. The novelty concerns introducing the inverse-based design

In this paper, an analytical model based on the Magnetic Equivalent Circuit (MEC) method is developed for a planar wound mover two-degree of freedom (2-DOF) resolver. Planar resolvers enable mass, volume, and complexity reductions for position contro
