Fatigue tests simulate the cyclic stresses that a material or component is subjected to during use, determining its strength limit and the number of cycles before failure. These tests are essential for ensuring the safety and reliability of structures and products used in critical sectors, allowing for the optimisation of materials and production processes.
Our equipment is capable of performing fatigue tests in tension, bending, compression and rotating bending, applying high-frequency stress cycles to components, products and complex structures.
The test can reach high pressures of up to 500 bar and a frequency of 15 Hz and can be performed with oil or coolant.

Axial (tension-compression) and rotary bending dynamic characterization utilizing MTS systems up to 250 kN and frequencies up to 100 Hz. High Cycle Fatigue (HCF) tests evaluate high-frequency stresses (>10⁵ cycles), while Low Cycle Fatigue (LCF) tests analyze plastic deformation and high loads at low cycles (<10⁵).
Cyclic validation on Automotive components, piping, manifolds, and cooling circuits with hydraulic pressures up to 500 bar and frequencies up to 15 Hz. Testing can be executed with oil or coolants inside environmental chambers and explosion-proof ATEX cells inerted with nitrogen for safe handling of flammable fluids.
Experimental study of crack propagation resistance utilizing compact tension (CT) specimens. The testing accurately determines the crack growth rate per load cycle (da/dN), identifying the threshold stress intensity factor (ΔKth) and the essential parameters ($C, m$) governing Paris Law equations.
