Understanding and controlling the sources of discrepancy between tests and simulations

By Team Eikosim | 1 March 2019

Adjustment and validation of simulations Simulation is crucial in the development, approval, and certification of industrial products and services. It is the foundation for strategic business decisions and projects, making experimental testing even more significant. Testing and output of measured results used to be a mere requirement for compliance demonstration, but now it serves as…


How to preview your test using Blender software?

Digital image correlation: The contribution of the global method

By Team Eikosim | 17 August 2018

Why a “global” method? Digital image correlation consists in measuring a displacement field between a reference configuration and a deformed configuration. There are two large families of algorithms to make this measurement: In the general case, the displacement field u(x) can be decomposed as a sum of functions of form Nm : where vα,m are…
