The use of resin film infusion (RFI) has been proven to reduce the cost of production of aircraft secondary sandwich structure. In this paper thermoelastic stress analysis (TSA) is used to assess the performance of full scale aircraft sandwich structure panels produced using both the conventional autoclave process and RFI. Finite element (FE) models of both panel types are developed and TSA is ...
this work presents thermoplastic analysis of fg rotating diskswith variable thickness and constant angular velocity. the solutions are obtained by variable material property (vmp) theory. in this theory, the domain is divided into some finite sub-domains in the radial direction, in which the properties are assumed to be constant and the form of the elastic response is used to solve elastic-plas...
Fs laser nanosurgery is characterized by the formation of low-density plasma followed by chemical effects of the free electrons (bond breaking), thermal effects, and compressive and tensile thermoelastic stress waves that produce transient cavitation bubbles. Dissection using oscillator pulse trains at >> 1 MHz is usually performed at energies well below the bubble formation threshold and thus ...
The evolution of the diffraction profiles during the fast thermoelastic deformation and structural transformations induced in a thin Ni film by short pulse laser irradiation is investigated in molecular dynamics simulations. Fast disappearance of the diffraction peaks characteristic for the initial crystal structure is related to the homogeneous nucleation and growth of liquid regions inside th...
This work focuses on the macroscopic behaviour of a large family of first-order phase transitions, including thermoelastic martensitic transformations, which are practically insensitive to thermal fluctuations and need to be driven by an external field. The Random Field Ising Model at T = 0 is used to carry out a detailed study of the dynamics and thermodynamics of this family of fluctuationles...
23 Abstract— The present investigation is concerned with effect of rotation on the wave propagation of generalized thermoelastic diffusion with one relaxation time. The exact expressions for temperature, the displacement components, stress components, chemical potential and concentration are obtained and represented graphically. Numerical computations are carried out and are obtained by using...
Internal stress associated with an oriented microstructure of defects are taken into ac count in the thermoelastic balance of martensitic phase transition. From this analysis a macros copic flow rule is determined for the TWME by using a phenomenological approach based on a yield criterion derived from Gibb's free energy expression. Experiments perfor med on a Cu-Zn-A1 polycrystalline alloy tra...
