YES … 2D DIC is Still Powerful & Effective
for Many Material Testing Applications!
Webinar
In a recent webinar hosted by ASM International, we presented several cases in which 2D DIC could be used effectively for in-plane mechanical testing, and we showed preliminary data to support this concept. The webinar received significant interest and led to many questions and requests for additional information! In this webinar, we present an expanded more comprehensive study in which detailed direct comparisons between 2D and 3D DIC measurements are carried out for selected material testing scenarios. We share results that demonstrate how 2D DIC can match (with negligible deviations) the output of 3D DIC, if done correctly. The goal is to promote the use of DIC and enable those with limited access to 3D DIC to still take advantage of 2D DIC and capitalize on the benefits it brings in enriching investigations of material deformation & failure.
Note: all project files (images, physical quantities, and even compiled DIC files) will be made available for everyone to process and further evaluate as needed. Some datafiles will be packages specifically for academia for use as training projects in classrooms.
How Effective is 2D DIC in Material Testing? Webinar
Digital image correlation (DIC) has become an important tool in material testing practices for the advanced characterization of materials in a wide range of applications. Despite that, the cost of a commercial 3D DIC system might still be a hurdle for many educational institutions, and even for some industrial establishments! 2D DIC is simple, inexpensive and easily attainable, yet it lacks the accuracy and depth of field capabilities of 3D DIC.
Despite this limitation, there are many testing scenarios where material deformation is planar and thus 2D DIC can capture material deformation with sufficient accuracy.
This webinar aims to address this important issue by presenting direct technical comparisons between 2D and 3D DIC measurements for selected material testing scenarios. The ultimate goal is to enable those with limited access to 3D DIC to still take advantage of 2D DIC and capitalize on the benefits it brings in enriching investigations of material deformation & failure.
High Strain Rate Tension Testing of Lightweight
Materials for Automotive Crash Simulations
Webinar
This webinar/demo sheds some light on the topic of high strain rate testing, and provides information supported by examples on how reliable high speed material characterization data can be obtained to support automotive CAE crash simulations. An overview of the latest generations of high speed testing machines and systems is first provided, then some testing technical details (test samples, test procedure, the use of DIC, issues with high speed testing, etc.) are discussed.
A live demonstration is also performed to provide hands-on experience and give the audience a feel of the details involved in high rate tension testing.
Finally, high speed testing results obtained with some of the latest generations of lightweight automotive materials are presented, and the influence of deformation rate on material behavior is discussed.
