## Abstract A leastβsquares mixed finite element method for linear elasticity, based on a stressβdisplacement formulation, is investigated in terms of computational efficiency. For the stress approximation quadratic RaviartβThomas elements are used and these are coupled with the quadratic nonconfor
When a muffler is modelled by the boundary element method (BEM), the transmission loss (TL) can be evaluated by either the conventional four-pole method or the recently developed three-point method. The three-point method produces only the transmission loss (TL), and nothing else. On the other hand,
