Antiplane deformation of a partially bonded elliptical inclusion
Kattis, M. A.; Providas, E.; Boutalis, Y.; Kalamkarov, A. (1997)A new method that introduces two holomorphic potential functions (the two-phase potentials) is applied to analyze the antiplane deformation of an elliptical inhomogeneity partially-bonded to an infinite matrix. Elastic ... -
An assessment of two fundamental flat triangular shell elements with drilling rotations
Providas, E.; Kattis, M. A. (2000)An approach for adding drilling rotations to the constant strain triangle, such that the added rotation stiffness contributes a minimum to the strain energy of the triangle is presented. The element is combined with a ... -
