Multi-axis testing – Italsigma

Prove multiasse

Multi-axis tests are advanced structural tests that apply simultaneous loads in different directions (axes) to a component or material. Unlike uniaxial tests, these simulate complex real-world operating conditions, evaluating fatigue strength, durability, and three-dimensional deformation—all of which are crucial for critical components such as rotors or structural parts.

Key Details:

Purpose:
To verify the fatigue strength and durability of materials under real-world loads, preventing unexpected failures.
Application:
These tests replicate real-world stresses on components—such as helicopter tail rotors—on the ground, ensuring compliance with flight certifications.
Technology:
They use servoactuators or biaxial/triaxial testing systems capable of applying forces and torques simultaneously.
Sectors:
Aerospace, automotive, and materials engineering.

These tests are essential for validating computational models during the design phase, ensuring that materials withstand millions of load cycles.
