Do Your Materials Change With Time?

This guest post on Innovation Intelligence is written by Renu Gandhi, Vice President of Business Development at Matereality, developer of material management software Workgroup Material DatabasePro. Matereality is a member of the Altair Partner Alliance.

Modern, non-linear materials are affected by their service environment. Over time, exposure to environmental factors and other effects of use can change the nature of a material.

Product developers are very aware of the risk of the potential change in material properties, and they are always trying to understand the impact it would have on their product. An awareness of the time-sensitive nature of candidate materials can help product developers make an appropriate choice before manufacturing begins.

One way to study how materials change is by conditioning the material and testing its properties over time. For example, the effects of temperature changes or exposure to chemicals that might be experienced by the material in a typical use case can be examined.

If you have test data available for the variables of interest, you can analyze the data to see if a material’s properties have changed. Of course, you can accomplish these data analyses manually, using a spreadsheet or statistical program, but analysis of such studies is facilitated by Matereality’s software for materials: use Matereality’s Compare functionality to visualize the changes.


Select material properties datasets to compare, then choose the results you want to analyze.

The software automatically analyzes a group of selected datasets and instantly provides graphical comparisons of all related properties, saving you considerable time that might have been spent performing cross-plots in Excel. Visualization tools that aid understanding include statistical error banding, which lets you visually gauge the spread of graphical data; rubberband zoom to examine specific areas of interest; and the ability to set explicit minimum and maximum values for either plot axis, or change either axis to log scale.

Graphical comparisons let you see instantly how the variables of interest affect material properties.
