Abstract We present a novel geometrically nonlinear EAS element with several desirable features. First, Petrov–Galerkin ansatz significantly improves the element's performance in distorted meshes without loosing simple strain‐driven format. Second, recently proposed mixed integration point strategy is employed to improve robustness Newton–Raphson scheme. Finally and most importantly, we enhance...
A deep inspiration (DI) temporarily relaxes agonist-constricted airways in normal subjects, but in asthma airways are refractory and may rapidly renarrow, possibly due to changes in the structure and function of airway smooth muscle (ASM). Chronic largely uniaxial cyclic strain of ASM cells in culture causes several structural and functional changes in ASM similar to that in asthma, including i...
Modifying stress-strain curves is one of the important topics in mechanical engineering and materials science. Real stress-strain curves should be modified after necking point as stress becomes three-dimensional after creation of throat, and consequently, equivalent stress should be used instead of axial one. Also, distribution of triple stresses across throat section is not uniform anymore, an...
