Symposium

C04: In situ characterization/testing

Belongs to:
TopicC: Characterization

The great potential of in situ observations/experiments is to study and to analyse the temporal evolution of ongoing deformation and damage processes in structural materials under defined loading conditions. However, the potential of in situ observation can be increased even more by combination with powerful complementary characterization techniques, e.g. electron backscattered diffraction, thermography, digital image correlation or acoustic emission measurements. The combination of various methods with their different resolution ranges in terms of lateral, spatial or time resolution can provide a deeper knowledge and understanding of the time sequence of microstructural processes. In addition, information gained through in situ experiments could contribute in a substantial manner to microstructure-based modelling of material behaviour under different loading conditions.

This symposium will mainly focus on both the development of new advanced in situ testing techniques and the further application of these techniques to understand the mechanical behavior of materials. Of special interest are combined experimental and simulation approaches. Topics of interest include but are not limited to:

  • In situ characterization/testing using optical microscopy, SEM, TEM, CT, X-ray diffraction, Synchrotron
  • Monotonic and cyclic testing; multiaxial testing  
  • Testing at elevated temperatures and under various environmental conditions
  • Evaluation of localized phenomena by use of digital image correlation, acoustic and thermal measurements or combined full-field measurements
  • Testing and understanding the deformation behavior of:
    • materials with different microstructure (from single to nano crystalline grain sizes) and/or crystal structure
    • microstructurally graded materials
  • Correlation between experiments and simulations
