“…This is because the material is brought to the melting and vaporization state almost instantaneously along isotherms ruled by the so called modified Bessel function of the second type and zero order as reported in [10]. Besides, Huang and Sun [11] state that, as compared to heating rate, cooling rates can be less dangerous for the material integrity since temperature decreases with exponential laws offering lower gradients in the tail of the melt pool. Therefore, the idea of the present paper is to generate combined pre-and-post-heating areas in which the weld material experiences less severe heating and cooling rates.…”

“…Due to the importance of the problem, it is still a hot research field until now. [3][4][5][6][7] Generally, spacecraft dynamics belongs to rigidelastic coupling dynamics. If thermal stress and thermal effect are considered further, it may cause more complicated rigid-elastic-thermal coupling dynamics.…”

Spacecraft dynamics belongs to rigid-elastic coupling dynamics in general. If thermal stress and thermal effect are further considered, it will cause the more complex rigid-elastic-thermal coupling dynamics. For the aforementioned kind of coupling dynamics, it is difficult to establish the basic equations directly. It has proved that a suitable way to study complex coupling problems is by work-energy theorem and the law of conversation of energy. Using the energy method, Hamilton principle of rigid-elastic-thermal coupling dynamics is established. The stationary value conditions of Hamilton principle of rigid-elastic-thermal coupling dynamics are derived. The physical meaning of the stationary value conditions is indicated. As an application of rigid-elastic-thermal coupling dynamics, the actual example of spacecraft is given to reveal that there existed thermal stiffening or softening problems in rigid-elastic-thermal coupling dynamics, just like dynamic hardening or softening problems in spacecraft dynamics.

“…The matrix-partition method was suggested by extending the existing unmixed-mixed scheme. The deformation states in the matrix phase can be represented with a set of mechanical variables for the respective parts of the partitioned matrix [3][4][5][6][7][8].…”

The viscoplastic behavior of the fiber-reinforced metal matrix composites under the thermomechanical loading is discussed in this study. The theories of micro-mechanics with the concepts of average stress and strain are adopted and developed to integrate matrix, coating and fiber properties for predicting the stress-strain response. It is reduced to a set of the ordinary differential equations of one order that can be resolved by the numerical solution algorithms based on the classical fourth order Runge-Kutta method.
