Verification of strain gradient elasticity computation by analytical solutions

As there are different computational methods for simulating problems in generalized mechanics, we present simple applications and their closed-form solutions verifying a numerical implementation. For such benchmark, utilize these analytical examine three-dimensional simulations by the finite element method (FEM) using IsoGeometric Analysis (IGA) with aid of open source codes, called tIGAr, developed within FEniCS platform. A study so-called wedge forces double tractions help to comprehend roles displacement solution as well significance comparing closed form given boundary conditions. It is found that results good agreement if considered. also presented how become necessary order maintain equilibrium strain gradient materials.
