Background

Nanomechanical testing has matured dramatically since the introduction and development of the original instruments and data analysis algorithms over two decades ago.

Much of this growth process has been driven by new markets and applications that dictate changes in the way that test results are analyzed and reported. Current high-throughput instrumentation generates large quantities of data that demand automated and statistical analysis tools. In addition, as the materials being studied have grown, so has the need for alternative models for analysis of test results. Hysitron has harnessed the power of OriginPro to create TriboAnalysis as an advanced data analysis and reporting tool to be used for all nanomechanical testing results.

Custom Models

Historically, most quasistatic nanoindentation experiments have utilized analysis models that make numerous assumptions regarding the contact conditions, such as purely elastic-plastic deformation.

Variations in experimental conditions and sample materials dictate differences in the way that results are analyzed. Numerous models have been developed for analysis of test conditions that exhibit different deformation modes, such as purely elastic, viscoelastic or viscoplastic indentations. The growth of instrumented indentation techniques into soft polymer and biomaterials applications introduces additional factors such as adhesive and porous contacts for which models have been and are being derived. A simple text editor or a powerful C-based code builder allows any analytical model to be utilized and automated for data analysis. In addition, alternative testing modes, such as creep or stress relaxation, nanoDMA® and scratch testing all require alternative analysis models and ways of viewing test results. Observation and fitting of any measured data, rather than simply load-displacement data, allows these alternative testing modes to be analyzed appropriately. For example, stress-relaxation requires an exponential fit to force-time data or nanoJKR requires a fit to stiffness load data.

TriboAnalysis provides an open architecture advanced analysis tool for implementation of any user definable functions or models that are appropriate for any material and test conditions.

Custom Data Observation

TriboAnalysis utilizes the power of OriginPro to provide a wide array of 2D, 3D and contour graph types for observation of results from indentation test arrays. Customizable plots allow creation of any look for presentations or publications. Any custom plot can be utilized to create a graph template that can be saved and used for future generation of similar style graphs. Observation of arrays of data through multi-dimensional observation and histograms reveals patterns within data that may not be clear from standard reporting methods. As seen to the right, two distinct phases become obvious in the steel material become obvious in a hardness histogram.

In addition, OriginPro allows image formats to be imported and analyzed via matrix math operations. This expands the capability of TriboAnalysis to allow visualization and quantitative analysis of images, including Scanning Probe images that are generated from Hysitron’s testing instruments.

Custom Automatic Report Generation

TriboAnalysis provides statistical analysis and reporting of data from automated testing. A report template can be customized to include the required information generated from automated testing, as well as template and information such as a user-definable logo, probe information and selectable tables and graphs. This “one-click” report generation allows a technician to quickly and easily generate automated report from automated testing results, thus minimizing user-intervention and potential user effects on the reported results.
