Assembly and disassembly mechanics of a spherical snap fit
《Theoretical & Applied Mechanics Letters》2023年第1期26-32,共7页Xiao-Lin Guo Bo-Hua Sun 
the financial support from Xi’an University of Architecture and Technology(Project No.002/2040221134)。
The snap fit is a common mechanical mechanism.We have studied the spherical snap fit carefully for its physical asymmetry,which is easy to assemble but difficult to disassemble.Because of the complexity of spherical s...

Effect of fluid elasticity on the numerical stability of high-resolution schemes for high shearing contraction flows using OpenFOAM
《Theoretical & Applied Mechanics Letters》2017年第1期41-51,共11页T. Chourushi 
Viscoelastic fluids due to their non-linear nature play an important role in process and polymer industries. These non-linear characteristics of fluid, influence final outcome of the product. Such processes though loo...

A generalized constitutive elasticity law for GLPD micromorphic materials, with application to the problem of a spherical shell subjected to axisymmetric loading conditions被引量：1
《Theoretical & Applied Mechanics Letters》2014年第2期74-82,共9页Koffi Enakoutsa 
In this work we propose to replace the GLPD hypo-elasticity law by a more rigorous generalized Hooke＇s law based on classical material symmetry characterization assumptions. This law introduces in addition to the two...
