Finite-Layer Method: Calculation of Interface Stresses in a Composite Panel Reinforced by T-Stringers

摘要

The finite-layer method is extended to the layered composite structures with partially bonded layers with different geometric characteristics. This makes it possible to perform a strength analysis of objects of more complex forms. The purpose of the study was to calculate the interface stresses arising in joints of composite parts and the transverse normal and tangential stresses in composite layers. Their values are necessary to estimate both the bond strength of the parts and the possibility of occurrence of internal delaminations in the composite.
