MCalibration®: Inverse Calibration

This half-hour, web-based class offers an overview of using inverse calibrations in MCalibration. This course will review how to set up MCalibration to run an inverse calibration, extract the data, and run the calibration.

Case study

High Rate Temperature Response of Polymers
Polymers exhibit significant temperature-dependent mechanical response. Veryst tested a PEEK material at multiple temperatures and calibrated the PolyUMod® Three Network (TN) material model for finite element simulation.
High Strain Rate Testing of Polymers
This case study demonstrates the testing and calibration of a polycarbonate material at a high strain rate of 1000 sec-1. The testing was done with the Split Hopkinson Pressure Bar (SHPB) system and the calibration is performed with Veryst Engineering’s MCalibration® software.
PEEK Temperature Dependence
PEEK materials are increasingly used in a variety of industries with elevated temperature applications. This example shows how Veryst Engineering developed a temperature-dependent, nonlinear model of PEEK behavior for use in commercial FEA codes.
Polymer Foam Testing & Modeling
Polymer foams may exhibit extreme strain rate-dependence due to their structure. The low stiffness means testing the materials at high strain rates is particularly difficult. Veryst has developed multiple test methods to test and model these materials with our PolyUMod® library.
Polymer Material Models in Different FE Packages
All commercial FE packages provide material models for polymers, but Veryst Engineering’s PolyUMod® material library has advanced material models at the leading edge of polymer mechanics. We demonstrate the accuracy of a PolyUMod material model with native material models from Abaqus, ANSYS, and LS-DYNA.


Customized Computational Solutions
Veryst uses its extensive expertise in simulation and analysis to develop customized computational solutions. Clients developing new materials or new production processes are at a disadvantage when suitable simulation tools are not yet available. Veryst can develop unique, customized solutions such as simulation applications ("apps"), new material subroutines, and custom algorithms.
Impact Simulation & Testing
Veryst offers expertise in simulation and testing of impact events with specialties including transient simulations, high strain-rate material characterization, modeling of failure mechanisms, and data processing and analysis. Veryst has served a wide range of industries in this area, such as consumer electronics, sports equipment, consumer appliances, and petrochemical engineering.
LS-DYNA Material Models
Veryst has designed test plans to calibrate many of the material models in the extensive LS-DYNA library. We have designed test plans for SAMP-1, Fu-Chang Foam, and the simplified rubber material model.
Material Modeling

Veryst has extensive experience selecting and calibrating material models to capture the most important aspects of material behavior for your specific material and conditions during use.  Using MCalibration®, a software tool origi


Veryst’s mechanical testing capabilities have been developed over the past decade and are motivated by the need for high quality data to characterize complex polymer behavior.  We tailor our test programs based on our deep understanding of polymer and material mechanics and the challenges complex

Tests by FEA Software
Veryst can specify a test program—a standard combination of tests—that captures your material’s response for use with a particular material model in a variety of finite element software packages. We have developed packages for many common constitutive models, but can customize the test plan to any model.
