Static and dynamic tests on materials and small components

Bovisa Campus, Building B13
via La Masa, 34 20156 Milano - Italy

Description

The laboratory is equipped with several resonant and universal testing machines for static and dynamic tests on metallic, composite and advanced materials. Each testing machine features extensometers with different gage lengths and temperature ranges, along with 2D and 3D measurement systems. Furnaces and environmental chambers are available to perform tests at low and high temperature.

Activities

Static and dynamic tests on materials and small components:

  • Tensile and compression static tests according to international standards or customized in order to fulfill the customer needs
  • High cycles fatigue (HCF) and low cycles fatigue tests (LCF). Temperature range: -40/+1000°C
  • Dynamic tests with customized load spectra
  • Static and dynamic tests for the characterization of the components (e.g. stiffness)
  • Further kinds of test (e.g. flexural, shear) or test conditions (temperature, standard) can be arranged upon request

Fracture mechanics:

  • KIc determination according to ASTM E399
  • JIc determination according to ASTM E1820
  • Measurement of Fatigue Crack Growth Rates according to ASTM E647 and under customized load spectra
  • Temperature range for Fracture mechanics tests: -100/+1000°C

Multi axial tests:

  • Biaxial and triaxial static tests, applied by means of three independent controlled actions: axial (max 250 kN), torsional (max 2200 Nm), pressure (max 100 MPa)
  • Biaxial and triaxial low cycle fatigue tests (LCF). Tests can be performed under strain control.
  • Biaxial high temperature low cycle fatigue tests (LCF) up to 1000°C
  • Axial-torsional high cycles fatigue (HCF) tests. Axial and torsional axial can be applied either in phase or out of phase
  • Dynamic tests with customized load spectra

Tests on polymeric, composite and advanced materials:

  • Static tests on composite materials according to ASTM standards (e.g. D6671, D5379, D6484, D695, D3410) and ISO (e.g. 14126, 14129)
  • Static tests on polymeric materials according to ASTM (e.g. D3039, D3518, D638) and ISO 527
  • Low cycles fatigue tests (LCF) and High cycles fatigue (HCF), e.g. ISO 13003
  • Other kinds of test (e.g. ISO 178, ASTM D7274) or test conditions (high/ low temperature, standard) can be arranged upon request
  • Adhesive testing (static e.g. ISO 14130, ISO 15024 and fatigue)

In collaboration with the interdepartmental laboratory HSR, it is also possible to perform dynamic characterization tests according to the ASTM D7136, D3763, ISO 6603, ISO 8256 standards.

Creep, Creep Crack Growth and Creep-Fatigue Crack Growth tests:

  • Creep strain analysis through extensometry of round section specimens at high temperature
  • Crack initiation and propagation analysis of pre-cracked C(T) specimens through potential drop system at high temperature
  • Crack initiation and propagation analysis of pre-cracked C(T) specimens in a creep-fatigue interaction context
