Crack Growth and Defect Assessment Engineering Services

This study investigated using numerical and experimental techniques to characterise the static and fatigue strength of a flat stiffened panel, designed as a Fibre Metal Laminate (FML) and made of aluminium alloy and Fibre Glass FRP. The full scale panel was tested under both static and fatigue bi-axial loads, applied by means of an in house designed and built multiaxial fatigue machine. The strain gauge outcomes from a preliminary static test were compared with the corresponding numerical results, achieving a satisfactory correlation. Crack propagation in the FML was also simulated. To overcome the lack of experimental information on the size of the delamination area an ‘‘inverse’’ procedure was applied to minimise the numerical and experimental growth rate differences.

Fracture & Crack Growth

Fracture & Crack Growth

BEASY Fracture & Crack Growth (FCG) is a breakthrough solution for engineers seeking precise fracture mechanics models for structural components. This innovative technology allows for damage-tolerant design assessment with accurate stress intensity factor (SIF) solutions and three-dimensional crack growth simulations, gaining vital insights into crack growth rates and shape evolution.



Revolutionise stress analysis models by scanning simulation models to pinpoint potential areas of crack growth. With BEASY Defect Scanner, engineers can scan stress models and easily gain insights into estimating critical crack sizes within areas of structures and components. These simulation models provide enhanced understanding of structural integrity and allow for predictive maintenance.
