Investigation of the stress distribution in a thick plate fabricated from the curved composite

摘要

In this work, The stress distributions in a thick plate fabricated from the composite material with periodical curved structure are studied. Under the periodical curved structure of the composite materials, the periodical curving of the reinforcing layers is understood. Investigations are carried out numerically by employing FEM and stress distributions in this plate are found with the use of exact equations of three dimensional theory of Elasticity. This plate occupies the region Ω = {0 ≤ x_1 ≤ l_1, 0 ≤ x_2 ≤ h, 0 ≤ x_3 ≤ l_3}.
