Fracture mechanics testing quantitatively evaluates a material's resistance to the propagation of pre-existing flaws or cracks under static or cyclic loading. Going beyond the limitations of traditional impact tests (such as Charpy V-notch), these investigations provide the critical engineering parameters (K, J, CTOD) required by modern structural design codes to prevent sudden catastrophic failures and accurately estimate component fatigue life.
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.

Measurement of plane strain fracture toughness (KIC) for high-strength or brittle materials. This standard test determines the critical stress threshold beyond which a pre-existing crack propagates unstably under static load, serving as a key parameter for aerospace, automotive, and structural engineering.
Cyclic dynamic testing essential for Damage Tolerance engineering concepts. This Fatigue Crack Growth analysis experimentally determines the crack propagation rate per load cycle (da/dN) in structures subjected to repeated stress, delivering the necessary parameters to predict component fatigue life.
Characterization of fracture initiation toughness in highly ductile metallic materials that undergo significant plastic deformation at the crack tip before propagation. The Jic parameter quantifies the critical energy required for crack growth, extending beyond linear elastic fracture mechanics validity.
Specialized testing for the qualification of structural steels and welded joints used under severe operational conditions. It measures the local displacement at the crack tip prior to fracture, delivering critical safety data for high-risk structures such as pipelines and offshore infrastructure.
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.
