ABSTRACTTransient temperature field of laminated plate which considering radiation is analyzed by laying temperature lines in every layer in this paper. Finite element equations are established by using high-order displacement field which considering shear effect based on the temperature analysis. Then thermally induced vibration of laminated plate is investigated by solving the finite element equation with numerical method. Compared with numerical results of ANSYS by using 3-D coupled element (SOLID5), the methods presented in this paper have a satisfied precision and better efficiency. It can give reference to the thermally induced vibration analysis of thin-large flexible laminated appendages of spacecraft.

In Fire

High temperature in fire have serious influences on the structural behavior of reinforced concrete structure, and causes damage in structure, even leads to overall collapse. By thermal and structural analysis using finite element method, the whole-course behavior of a reinforced concrete bridge in fire is simulated, and the transient temperature field, deformation and stress is discussed. These information supply the basis for fire resistance of concrete bridge design.

This paper is the result of research and operation modeling of the new systems for cooling of cutting tools based on thermoelectric module. A copper inlay with thermoelectric module on the back side was added to a standard turning tool for metal processing. For modeling and simulating the operation of thermoelectric module, finite element method was used as a method for successful solving the problems of inhomogeneous transient temperature field on the cutting tip of lathe knives. Developed mathematical model is implemented in the software package PAK-T through which numerical results are obtained. Experimental research was done in different conditions of thermoelectric module operation. Cooling of the hot module side was done by a heat exchanger based on fluid using automatic temperature regulator. After the calculation is done, numerical results are in good agreement with experimental. It can be concluded that developed mathematical model can be used successfully for modeling of cooling of cutting tools.

This paper carries out forced vibration analysis of graphene nanoplatelet-reinforced composite laminated shells in thermal environments by employing the finite element method (FEM). Material properties including elastic modulus, specific gravity, and Poisson’s ratio are determined according to the Halpin–Tsai model. The first-order shear deformation theory (FSDT), which is based on the 8-node isoparametric element to establish the oscillation equation of shell structure, is employed in this work. We then code the computing program in the MATLAB application and examine the verification of convergence rate and reliability of the program by comparing the data of present work with those of other exact solutions. The effects of both geometric parameters and mechanical properties of materials on the forced vibration of the structure are investigated.
