“…Overall, there are two basic material models widely used in theoretical analysis within the engineering profession. One of these models is Bert's model [3] for orthotropic materials, which is based on the criterion of positive-negative signs in the longitudinal strain of fibers, and is therefore widely used for research on laminated composites [4][5][6][7][8][9]. Another model is Ambartsumyan's bimodular model for isotropic materials [10,11], which is based on the criterion of positive-negative signs of principal stresses.…”

Abstract. The paper provides the calculation theory of an arbitrary supported and arbitrary loaded reinforced beam filled with bimodulus material. The formulas determining normal stresses, bending moments, shear forces, rotation angles and a deflection of a rectangular crosssection beam reinforced with any number of bars aligned parallel to the beam axis have been obtained. The numerical study has been carried out to investigate an influence of a modulus of subgrade reaction on values of maximum normal stresses, maximum bending moments and a maximum deflection of a hinged supported beam loaded with a point force or uniform distributed load. The estimation is based on the method of initial parameters for a beam on elastic foundation and the Bubnov-Galerkin method. Values of maximum deflections, maximum bending moments and maximum stresses obtained by these methods coincide. The numerical studies show that taking into consideration the bimodulus of material leads to the necessity to calculate the strength analysis of both tensile stresses and compressive stresses.

“…Some materials, such as concrete, polymer and composites, usually exhibit different mechanical responses in tension and compression in that they have different tensile and compressive moduli [1][2][3]. This kind of material is usually called bi-modulus material which has been reported in a lot of literature and monograph.…”
