2020 MRS Spring Meeting

Call for Papers

In March of this year, MRS leadership made the difficult decision to cancel the 2020 MRS Spring Meeting in Phoenix for the safety and well-being our members, attendees, staff and the materials community, and to reschedule as much of the program as possible into a special 2020 Joint MRS Spring and Fall Meeting.

This one-time-only joint event will take place in Boston, from Saturday, November 28 through Friday, December 4—expanding by one day to provide programming capacity. The program flow for each symposium is under development and will be announced in early July.

Symposium ST02-In Situ Mechanical Testing of Materials at Small Length Scales, Modeling and Data Analysis

In Situ small-scale mechanical testing enables new insights into deformation and failure mechanisms of a wide range of materials including bulk materials, monocrystalline materials, thin films as well as low-dimensional materials. The direct observation of deformation phenomena in controlled geometries helps to unravel fundamental deformation processes. In addition, the influence of microstructure features (e.g. grain boundaries, interfaces, dislocation density) or crystal structure (e.g. glide systems, crystal anisotropy, elasticity) on the overall deformation properties of a material can be directly evaluated. Newest experimental techniques allow performing mechanical measurements under controlled external conditions including at high or low temperature, gas environments or under radiation exposure. In addition, advances in deformation devices including MEMS have established new areas such as in situ tribology or in situ fatigue and fracture experiments.

The current session will focus on recent advances in nanomechanical testing, including experimental techniques that allow measurements with high throughput, at variable strain rate or in-operando. A special focus will be set on developments in the field of diffraction and imaging methods that allow to extract quantitative mechanical data from local microstructure components or nano-sized objects under load at high spatial resolution. This includes new detector developments facilitating faster imaging or increased frame rates for diffraction pattern acquisition. New analysis routines including machine learning will be addressed that allow to obtain quantitative information from large datasets. Finally, the session will highlight the comparison of experimental data with results obtained from modelling using MD, DDD and crystal plasticity FE methods.

Topics will include:

  • Fundamental studies in mechanical and indentation testing (crystal plasticity, phase transformations,...)
  • In Situ techniques (synchrotron, electron microscopy, light microscopy, …)
  • High throughput small scale testing
  • Geometries for deformation, wear, fatigue and fracture testing
  • Novel preparation methods for micro- and nanoscale objects for small scale testing (FIB, lithography, …)
  • Advances in deformation testing devices including MEMS
  • High temperature and environmental testing
  • High resolution local strain and stress measurement during in situ Deformation​
  • Modelling of deformation using MD, DDD and crystal plasticity FE methods
