外文摘要：The classical adhesive contact models belong to isothermal adhesion theories,where the effect of temperature on adhesion was neglected.However,a number of experimental results indicated that the adhesion behaviors can be significantly affected by temperature.In this paper,the two-dimensional non-slipping anisothermal adhesion behaviors between two orthotropic elastic cylinders are investigated within the framework of the Johnson-Kendall-Roberts theory.The stated problem is reduced to the coupled singular integral equations by virtue of the Fourier integral transform,which are solved analytically with the analytical function theory.The closed-form solutions for the stress fields in the presence of thermoelastic effect are obtained.The stable equilibrium state of contact system is determined by virtue of the Griffith energy balance.The effect of temperature difference on adhesion behaviors between orthotropic solids is discussed.It is found that the difference between the oscillatory and non-oscillatory solutions increases with increasing the degree of anisotropy of orthotropic materials.The oscillatory solution cannot be well approximated by the non-oscillatory solution for the orthotropic materials with relatively high anisotropy.
