Material Modeling


iCAAM offers material modeling as a service. Producing high quality physics-based material models for materials is essential to meaningful simulation, but available modeling may be insubstantial. Contact us to have your material modeled.


In order to model material accurately, the underlying microstructure of the material must be measured, quantified, and represented. MRL has developed tools that take the higher order statistical microstructural representations and use this information as a physical descriptor for modeling strength and fatigue performance.


Quasistatic Material Models

While some materials may demonstrate isotropic stiffness, many materials do not. Capturing deviation from isotropic behavior is crucial to accurate modeling efforts. MRL makes use of the full stiffness matrix when modeling material. MRL uses EBSD and tensile testing to calibrate its models for:


  • Isotropic Materials
  • Anisotropic Materials

Fatigue Models

Accurately modeling fatigue performance of is a complex endeavor due to the complexity of the physics at play. MRL has developed a fatigue model that captures the impact of:


  • Microstructure
  • Defects (defect size, aspect ratio, extreme defect prediction)
  • Stress Ratio
  • Spectrum Loading

Machine Learning Enhanced Microstructural Characterization


MRL's iCAAM software is capable of rapidly identifying microstructural bodies (grains and particles), performing automatic segmentation, quantification, and representation of the microstructure in just seconds.

MRL has developed tools that take the higher order statistical microstructural representations and use this information as a physical descriptor for modeling strength and fatigue performance.


Microstructure Segmentation

Segmenting microstructure is a process that often demands manual intervention, if not manual segmentation altogether. iCAAM has a powerful computer vision tool used to automatically segment microstructure. Beyond this, the software rapidly generates 2-pt correlation maps, chord length distribution figures, as well as average microstructure size, median size, standard deviation, and more. The tool is extremely rapid, turning hours of manual segmentation into fractions of seconds.



Texture Evaluation

Measuring crystallographic orientation is paramount to several material models and obtaining crucial information about a material's processing history. iCAAM is outfitted to use standard *.ANG files and can rapidly produce IPF Maps, Pole Figures, C-Maps, and additonal information about microtextured regions. This software can handle hundreds of millions of points with no issues, and keeps all of your EBSD information in an malleable database for rapid access and comparison.

Process Simulation


iCAAM offers linkages with commercial finite element solvers MARC and ABAQUS for process simulation. The thermomechanical path to metal forming will determine the location specific microstructure of the metal which controls material performance. iCAAM uses a technique developed in-house called Crystal Tracking which allows iCAAM users to determine local thermal gradients and rates of solidification to determine local microstructure rapidly.
