- Sponsored Workshop: Using Simulation Tools to Drive Advances in Mechanical Materials Testing
By Double Precision Consultancy
Material models in the simulations that we run need populating with reliable material data. However, if unavailable, obtaining the mechanical material properties of metals (plasticity parameters, for example) using conventional mechanical testing equipment can be cumbersome, expensive, and time consuming. A new method, developed by scientists from the University of Cambridge, has recently emerged as an alternative. Termed "indentation plastometry", the method is simpler, quicker, and cheaper than conventional mechanical testing methods; for instance, metal stress-strain curves can be obtained in just a few minutes, using small samples with minimal preparation. In this workshop, we’ll review the underlying methodology, and we’ll cover how we leveraged the power of the COMSOL Multiphysics® software, cloud computing, machine learning, and COMSOL Compiler™ to support the development and release of a commercially available indentation plastometer for our client, Plastometrex. We will also perform a live demonstration of the indentation plastometer in operation.

- STOP Analysis with the Ray Optics Module
The high-fidelity simulation of optical systems in particularly harsh environments must account for the impact of thermal and structural effects on optical performance. For example, the large temperature changes found in outer space and high-powered laser focusing systems can change the refractive indices due to thermo-optic dispersion. Under extreme conditions, the elements of the optical system may experience significant thermal stress, causing physical deformation and a further degradation of the image quality.
In this minicourse, you will learn how to use the Ray Optics Module to perform coupled structural-thermal-optical performance (STOP) analyses of optical systems. You will learn how to use COMSOL Multiphysics® to compute temperature and displacement fields using the finite element method (FEM) and then couple these fields to a ray optics simulation using built-in optical dispersion models. The distinction between unidirectional and bidirectional couplings in STOP analysis models will also be explained.

The most common type of study for these systems is the time-dependent study, but we will also briefly look at electrochemical impedance spectroscopy (EIS) studies.
