The sensitizing parameter values are determined by the single-element strain energy test. The reference solutions used are of bending mode types and their application removes the so-called parasitic shear behavior. A stiffness matrix of good quality is obtained corresponding exactly to an earlier formulation using incompatible modes.</p>}, number={3}, journal={Rakenteiden Mekaniikka}, author={Freund, Jouni and Salonen, Eero-Matti}, year={2019}, month={syys}, pages={192–199} }
