Originální abstrakt

The motivation for this work is a desire for deep understanding of the structural failures in a composite glider wing, which has been tested in the laboratories of the Institute of Aerospace Engineering, Faculty of Mechanical Engineering, University of Technology in Brno. To understand the causes of the encountered failures, one has to consider the effects of all the stages in design, manufacturing and testing of the wing. This paper focuses on the design stage only. Presented facts are obtained from finite element analysis. The geometry used for the analysis is that of tested specimens. This allows validating the results by comparison of deformation and strains measured during the laboratory tests. Analysis starts with simple I-beam loaded by three-point-bending. In the next step a cantilever is added. Several more modifications follow, changing the I-beam to the wing. Case evaluation considers the interaction between normal (material direction 1) and inter-laminar shear stresses in the upper flange. The goal of this paper is quantifying the effect of each design change in the wing structure and loading on the stress plane S1-T31.
