Composite materials are used as structural components in many disciplines. The structures
may become prone to damage during the service conditions. The damage types are surface …

Late detection of cracks can lead to serious failures and damages of drilling components,
especially drill pipes and drill bits. Currently, the widely used method of repairing rotary …

The influence of various crack inclination angles on the mode shape, rotational stiffness at
the cracked cross section and the stiffness of the cracked cantilever beam was investigated …

We propose herein a mathematical relation to calculate the severity of transverse cracks
which affect a prismatic beam. It is known that the damage severity depends on the depth of …

The main objective of this research is to detect crack at different positions of the thin metal
cantilever plate based on the natural frequency. Most of the researchers have investigated …

In the current paper we aim to evaluate the accuracy of a previously developed method to
determine the frequency drop of a cantilever beam having an L-shaped damage with a well …
