In many industries, when replacement of a part is not possible or economic, the repair is
done. One of the best methods for repairing metal and composite parts is using composite …

Recently, there has been a huge interest in materials that can self-heal, as this property can
potentially increase materials lifetime, reduce replacement costs, and improve product safety …

Setting inspection intervals based on an accurate prediction of fatigue crack sizes is
essential for sustaining the integrity of aeronautical structures. However, the fatigue crack …

In this paper, parameters affecting the performance and durability of a one-sided composite
patch for mixed-mode crack repairing is investigated, considering different thicknesses of the …

The evaluation of the reliability and the lifetime of aerospace components has become an
important segment of the design stage. The aeronautical components are subjected to …

Two major helicopter blade structural defects may disturb flight stability before crashes: ie
debonding of the isotropic skin enveloping the orthotropic materials of the leading edge (UD …

A new destructive method for the quantitative determination of damage accumulation in the
stress concentration zone has been proposed and verified. Damage accumulation in the …

This paper presents a detailed analysis of the failure of compressor blades from a helicopter
engine. The analysis presented in this paper is a result of a preflight inspection carried out …

This paper investigates the strenght of a conceptual main rotor blade dedicated to an
unmanned helicopter. The blade is made of smart materials in order to optimize the …

The novel non-destructive method for quantitative description of low-cycle fatigue damage
accumulation is expanded to a case of contact interaction in the stress concentration area …
