Vliv aproximačních funkcí, integrace a Poissonova čísla na vlastnosti některých 2D konečných prvků.
Displacement response of bilinear and biquadratic isoparametric elements is investigated in terms of eigenpairs of stiffness matrices. Analysed matrices are computed for various values of Poissons ratio, degrees of numerical integration and various types of constraints on strain and/or displacement components. Constraints are imposed via projection methods. Stress components and stress invariants corresponding to eigenvectors are also analysed.
