Rolling resistance dictates a large part of the energy consumption of trucks. Therefore, it is necessary to have a sound understanding of the parameters affecting rolling resistance. This article proposes a semi-physical thermodynamic tyre rolling resistance model, which captures the essential properties of rolling resistance, such as transient changes due to temperature effects and the strain-amp...... hiện toàn bộ
Multiphysical time-dependent creep response of FGMEE hollow cylinder in thermal and humid environmentSpringer Science and Business Media LLC - Tập 25 - Trang 151-173 - 2019

In this paper, we investigate the history of radial displacement, stresses, electric potential, and magnetic potential of a functionally graded magneto-electro-elastic (FGMEE) hollow cylinder subjected to an axisymmetric hygro-thermo-magneto-electro-mechanical loading for the plane strain condition. The material properties are taken as a power-law function of radius. Using stress-displacement rela...... hiện toàn bộ
Nonlinearly Viscoelastic Behavior of Polycarbonate. II. The Role of Volumetric StrainSpringer Science and Business Media LLC - Tập 6 - Trang 301-322 - 2002
W.G. Knauss, W. Zhu
The creep responses of (bisphenol A) polycarbonate at 80°C undercombined two-dimensional shear with superposed tensile and compressivestress states were measured on Arcan specimens in the nonlinearlyviscoelastic regime. Of particular interest is the influence of thedilatational deformation component on the nonlinearly viscoelastic creepbehavior. Because the nonlinear material response determines t...... hiện toàn bộ
Thermodiffusion interactions in a homogeneous spherical shell based on the modified Moore–Gibson–Thompson theory with two time delaysSpringer Science and Business Media LLC - - Trang 1-22 - 2023

The main objective of the present paper is to investigate the relationship between the thermal processes and diffusion in thermoelastic solids. For this reason, a new model of thermo-diffusion interactions has been derived, which, unlike the traditional models, allows the thermo-diffusion waves to propagate at finite speeds. The Moore–Gibson–Thompson (MGT) equation is an essential part of the prop...... hiện toàn bộ
A fractional derivative approach to full creep regions in salt rockSpringer Science and Business Media LLC - Tập 17 - Trang 413-425 - 2012

Based on the definition of the constant-viscosity Abel dashpot, a new creep element, referred to as the variable-viscosity Abel dashpot, is proposed to characterize damage growth in salt rock samples during creep tests. Ultrasonic testing is employed to determine a formula of the variable viscosity coefficient, indicating that the change of the variable viscosity coefficient with the time meets a ...... hiện toàn bộ
