Here we show how the idea of conjugate approximations can be used as a means to obtain a formulation of mixed-dimensional <br />coupling between shells and solids. Our method is consistent with respect to the principle of virtual work<br />and does not depend on additional computational parameters, an augmentation of a potential-energy functional by introducing new unknowns, or computations over auxiliary meshes.</p>}, number={4}, journal={Rakenteiden Mekaniikka}, author={Malinen, Mika and Råback, Peter}, year={2023}, month={helmi}, pages={95–115} }
