[1] It is known that GPS time series contain a seasonal variation that is not due to tectonic motions, and it has recently been shown that crustal seismic velocities may also vary seasonally. In order to explain these changes, a number of hypotheses have been given, among which thermoelastic and hydrology‐induced stresses and strains are leading candidates. Unfortunately, though, since a genera...

In the present work, we have proposed a very simple model to predict thermoelastic properties of nanosolid, nanowire and nanofilm Selenium, Copper, Silver, Lead, Tin, Zinc Nickel elements with variation temperature at their different sizes. our study, it is observed that compression (V/V0) increases in nanospheres, nanowires nanofilms considered elements. The rate increment highest for nanosoli...

: In this paper, a nonlinear model of clamped-clamped microbeam actuated by electrostatic load with stretching and thermoelastic effects is presented. Free vibration frequency is calculated by discretization based on DQ method. Frequency is a complex value due to the thermoelastic effect that dissipates the energy. By separating the real and imaginary parts of frequency, quality factor of therm...

In the present paper, nonlinear radial and hoop thermoelastic stresses analysis of a disk made of FGMs material is investigated. According to this purpose, finite element method is used. In the present method, second-order one-dimensional element (with three node points) is proposed. The geometrical and stress boundary conditions are defined in the state of non-existence of external pressure an...

A level set based shape and topology optimization framework is used to study the effect of graded interfaces in the optimization process of micro-architectured multi-materials. In contrast to previous studies interfaces are considered as smooth transition between phases instead of a sharp delimitation between two phases. A study on extreme thermoelastic properties of 2D isotropic composites is ...

Thermoelastic instability in an automotive disk brake system is investigated experimentally under drag braking conditions. The onset of instability is clearly identifiable through the observation of nonuniformities in temperature measured using embedded thermocouples. A stability boundary is established in temperature/speed space, the critical temperature being attributable to temperature-depen...
