In the present paper we consider the problem of steady thermoelastic oscillations in a linear theory of plane elasticity with microstructure where disturbance is represented by a train of harmonic waves. The corresponding boundary value problems of Dirichlet and Neumann type are formulated and solutions are obtained in the form of integral potentials using… (More)
Reduction of a differential algebraic equation (DAE) system to an ordinary differential equation system (ODE) is an important step in solving the DAE numerically. When the ODE is obtained, an ODE solution technique can be used to obtain the final solution. In this paper we consider combining index reduction with projection onto the constraint manifold. We… (More)
This paper proposes a novel data structure for equation-based plant models. The data structure facilitates the plant modelling process starting from physics-based component creation through model simplification to Modelica model export.
