What is LW Finder?
LW Finder takes the guesswork out of strain gauge placement by finding the best locations to place strain gauges and predicting measurement error.
LW Finder is for structures that are expected to have a relatively linear relationship between load and measured strain. The Extra Errors module provides additional support for structures with non-linear effects, such as plastic deformation. LW Finder compensates for non-linear behavior in a structure and can be configured to take into account the properties of an individual strain measurement setup.
Additionally, this software allows users to prioritize the load cases that have minimum error and select gauge locations accordingly. Finally, the error prediction allows engineers to know ahead of time if the test will provide data of sufficient quality. This means better risk management and fewer disruptions to the project schedule due to unexpected bad test results.
