DatapointLabs and Matereality are attending more than half a dozen technical meetings and trade events through June 2014. The importance of verification and validation in the context of manufacturing simulation forms the focal point of presentations prepared for CAE- and FEA-related events.

Hubert Lobo will deliver Providing an Experimental Basis in Support of Finite Element Analysis at the SIMULIA Community Conference in Providence, RI, USA. DatapointLabs is also a conference sponsor, so be sure to stop by our booth if you're attending the event.

The use of CAE in design decision-making has created a need for proven simulation accuracy. The two areas where simulation touches the ground are with material data and experimental verification and validation (V&V). Precise, well designed and quantitative experiments are key to ensure that the simulation initiates with correct material behavior. Similar validation experiments are needed to verify simulation and manage the risk associated with this predictive technology. < Done

The Swanson Engineering Simulation Program in the Sibley School of Mechanical and Aerospace Engineering at Cornell University has been established with the goal of integrating computer-based simulations into the curriculum in a systematic manner. As part of the study of classical beam theory, an aluminium beam is deformed to a specific load. Theoretical strains are calculated at certain points along the beam using beam theory, and then verified by using strain gauges placed at these points on the beam. This experiment is then extended to simulation of the same test setup in simulation software, where strains are analyzed at the same points. Discrepancies between the simulation, theory, and strain gauge results have often plagued the test, especially when incorporating more complex beam design. Through use of digital image correlation (DIC) it is possible to pinpoint some of the problem areas in the beam analysis and provide a better understanding of the localized strains that occur at any point in the deformed beam. The use of DIC provides a full field validation of simulation data, rather than a single spot check that strain gauges can provide. This validation technique helps to eliminate error that is associated with strain gauge placement and the possibility of missing strain "hot spots" that can arise when analyzing complex deformations or geometries. < Done

Brian Croop will deliver Validation of Simulation Results Through Use of DIC Techniques at the ANSYS Conference & CADFEM Users' Meeting in Nuremberg, Germany. DatapointLabs is also an exhibitor, and we would be happy to meet with you during the event.

It has long been desired to quantify the accuracy of simulation results. Through developments in digital image correlation (DIC) techniques, it is now possible to quantify the deviation between simulation and "real life" experimentation. In this paper, three-dimension DIC measurements of deformed parts are compared to deformed surfaces predicted in simulation. Using DIC, it is possible to import deformed surface elements from simulation and map the magnitude of deviation from the measurements of the actual deformed shape. < Done

If you support a variety of CAE/FEA codes in your work, DatapointLabs introduces new Multi-CAE TestPaks to more efficiently meet your need for the right data, in the right formats to accomplish injection molding and crash simulations. Now you can order a single set of tests to generate all of the required data for a specific purpose, no matter which supported software package – or packages - you might be using. The Multi-CAE TestPaks save you both time and money, compared to ordering tests to produce the required data for each software package individually.

Find the new Multi-CAE TestPaks in our expanded online Test Catalog:

• Multi-CAE Molding – Test results include the data required to create material input files for Moldflow, Moldex3D and Simpoe simulations. Material input files for each of these software packages, as well as for SigmaSoft simulations, also are provided.
• Multi-CAE Crash – Test results include the data required to create material input files for LS-DYNA, Abaqus, and PAM-CRASH simulations. Material input files for each of these software packages also are provided.

When you order a Multi-CAE TestPak, we deliver your material properties data along with the associated material cards to your Matereality database. You can take advantage of Matereality's CAE Modeler software to fine-tune the material model inputs for your CAE applications, if desired. Then save your formatted material cards in the Material Model Library for later reference or reuse.
