Thermo-Mechanical Characterization using Non-Contact Deformation Measurement Techniques


Our state-of-the-art “High Temperature Non-Contact Material Characterization” test system, initially developed to measure surface profiles of components in-situ, up to temperatures as high as 1200 ℃, has evolved into a mechanical characterization tool to handle diverse materials like ceramics, metals, glasses, polymers, composites etc., under diverse environmental conditions like oxidizing, reducing, inert, vacuum, humid and ambient conditions. Choice of 9 different sensors to suit specific customer requirements makes this test set-up highly customizable.

Enhancements to this non-contact test system include handling higher temperatures up to 1600oC to measure deformation profiles, yielding accuracies close to few tens of a nanometer in out-of-plane deformation measurements.

Industries having high degree of interest in thermo-mechanical tests at elevated temperatures including Energy, Aerospace, Defense, and Automobile in addition to R&D institutions and academics involved in high temperature material development and characterization will find this test system indispensable.

Challenges: High temperature (>1000 ℃) material/mechanical characterization of ceramics, metals and alloys subjected to large deformations place challenging requirements on measurement systems. Accurate measurement of time and/or load dependent deformed profile/curvature of entire sample (e.g. during creep test) is essential to obtain complete information to characterize the material.

Our Solution: A novel “non-contact” 2-D/3-D differential profile measurement technique overcomes limitations of point based techniques (strain gauges, LVDTs etc.) by capturing entire deformed profile in-situ. This proprietary technique enables measurement of entire sample profile (deformation) including support displacements at any given instant in time, up to testing temperatures of 1600 ℃ in-situ, thereby eliminating errors related to boundary conditions (support/reference shift).

Technoconfluence Challenges: Characterization of glasses near their glass transition (Tg) and metals near their melting point require accurate measurements of deformed sample shapes and time lag with respect to loading profile.

Our Solution: Capability of one-sided differential thickness/gap measurements enables characterization of glasses above their glass transition (Tg) by placing samples between transparent plates. Time history of change in thickness (deformation) with respect to applied load profile is captured accurately. In addition to thickness change, lateral deformation time history provides complete information about the viscoelastic behavior of the material.
 
  • Impulse Test (natural frequencies and mode shapes)
  • Forced Excitation/vibration test
Challenges: In a typical forced excitation test, most of the actuators and accelerometers cannot be used at temperatures above few hundred degrees (>200 ℃) and sample excitation and associated frequency measurements at high temperatures pose significant challenges. Even an impulse (ping) test requires frequency measurements using accelerometers or other sensors limiting the applicability of tests to few hundred degrees.

Our Solution: Our unique differential displacement measurement captures entire profile thereby providing complete information of frequencies and mode shapes. For very accurate resonant frequency measurements, a specialized forced excitation test is also available as add-on in our vibrometry test suite.

Challenges: Typical profile measurements on parts at room temperature may not be valid at high temperatures (>1000 ℃) where profile changes occur due to process related residual stresses, density gradients across thickness or incomplete processing of parts etc. At high temperature, there is always a possibility of shift in the reference against which profile is measured leading to significant errors using conventional measurement technique.

Our Solution: Our in-situ measurement technique captures specimen/part profiles at high temperatures and under varied operating conditions (like oxidizing, reducing, humid etc) to measure profile changes in real time thus enabling accurate control of process parameters. Options are available for 3-D scan/ simultaneous capture of highly featured surfaces and real-time curvature measurements up to 1600 ℃.
