Fracture mechanical testing analyses the behaviour of materials in the presence of defects or cracks, evaluating parameters such as fracture toughness, crack growth under static or cyclic loads, and crack propagation speed, expressed as linear length per cycle, once the stress (ΔK) has been fixed.
This test is carried out at room temperature, using suitable test specimens (CT), and allows for improved material design and selection, preventing structural failures.
The elastic fracture mechanics test is carried out in accordance with ASTM E647, the purpose of which is to determine the threshold stress state (ΔKth) below which the crack propagation rate can be considered negligible, as well as the coefficients ‘C’ and ‘m’ that characterise Paris's law.
Our testing laboratories operate in compliance with the UNI CEI EN ISO/IEC 17025 standard, with certification issued by Accredia, the Italian Certification Body, as Test Laboratory No. 1286.

Measures the resistance of a material to crack propagation under static load conditions. The KIC parameter is essential for designing structures subject to critical stresses, such as aircraft, vehicles and infrastructure.
Analyses the propagation speed of a crack under cyclic loading conditions, simulating the effect of prolonged use on structural materials. It is used to predict the operational life of components.
Evaluates the behaviour of ductile materials in the presence of cracks, determining the JIc parameter, which describes the energy required for fracture propagation. It is crucial for materials with high plastic deformation capacity.
Measures the deformation at the crack tip before propagation, particularly useful for structural materials used in critical conditions, such as steels for offshore infrastructure and gas pipelines.
We evaluate the resistance to fatigue crack propagation on metallic and composite materials, simulating cyclic stresses to predict the service life of the component.
We measure the behaviour of materials under axial load, determining mechanical properties such as strength, elongation and elastic modulus on metals, polymers and composites.
We evaluate the strength and stiffness of materials subjected to bending stresses, which is useful for estimating the response to transverse loads in structural applications.
We determine the shear strength characteristics in specific planes, which are essential for analysing the performance of laminates and multilayer structures.
We analyse the response of materials to compressive stresses to detect properties such as yield strength, elastic modulus and deformation resistance.
All analyses can be structured in a completely customised manner, based on customer requirements. We offer tailor-made tests for materials, conditions of use and required regulations, ensuring reliable and targeted results.
