在本文中,我们提出了一个能量一致的混合时空离散热力耦合连续动力学,这是直接从总能量本身。与标准时间近似相比,我们获得了与粘弹性[1]相同的优点,即数值稳定性和时间步长无关的平衡律以及定性解。(© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA,魏因海姆)
In this paper, we present an energy consistent hybrid space‐time discretisation for thermomechanical coupled continuum dynamics, which is directly derived from the total energy itself. In comparison to a standard time approximation, we obtain the same advantages as for viscoelasticity [1], which are numerical stability and time step size independent balance laws as well as qualitative solutions.
