| Summary: | The calculation of fiber-reinforced concrete is performed by the finite element method using the stresses approximations. The solution is based on the additional energy functional. The nodes equilibrium equations are obtained using the possible displacements principle. To take into account the nonlinearity of concrete deformations, an orthotropic model is used in the plane case. The solution of the nonlinear problem is performed by the method of variable elasticity parameters. The paper gives a calculation result of a tension specimen. |
