  An algorithm allowing one to design a minimum-weight cross section of a layered composite shell with a specified contour geometry and given applied loads is proposed. The cross section has a closed contour symmetric with respect to the vertical axis and is divided into four parts-panels (two side panels and the upper and lower ones). The stacking sequences, the reinforcement angles of layers, and the thickness of different panels are distinct. To refine the solutions obtained by using a rough search method, a new genetic algorithm permitting one to find a number of equivalent optimum and close-to-optimum solutions in a short period of time is suggested. A formalization or coding scheme of solution of the problem is developed in the form of a specific structured vector.

  Fracture mechanics and strain energy release rate approach have been widely used for characterizing delamination in composite materials. This paper focuses on extending this approach to delamination at bi-material interface of GRFP and CRFP. Combination of these materials is a common design practice in small aircrafts and enables the utilization of carbon composite materials superior mechanical properties and glass composite lower cost. Modification of FRMM (Fixed Ratio Mixed Mode) testing method was used in order to get critical strain energy release rate in various levels of mixed mode (mode I / mode II). Beam theory analysis with conjunction of VCCT (Virtual Crack Closure Technique) was utilized for establishing equations for previously mentioned test method. Another modification of common testing procedure was application of Aramis photogrammetry system during the measurement of crack tip propagation in a specimen and following image post-processing by Python programming language.

  Acoustic emission is a technique to monitor defect formation and failures in structural materials used in services or laboratories. Moreover, the method has been developed and applied in numerous structural components for monitoring and failures localization. Article describes fatigue tests of wing segments and static wing test and their results. Mainly the process and results of monitoring by acoustic emission are described. Possibility of method application on large structures, advantages and disadvantages are presented.

  Increasing possibilities of simulation cause enhancement of the safety requirements in aerospace engineering. The trend did not avoid glider cockpit structures too. The investigation of a cockpit resistance during the emergency landing condition is always an important area of interest. In former times the cockpit design was the result of experience and tests. Now, there are a several finite element methods (FEM) systems for simulation of emergency landing condition.
