Welcome to contact.​engineering

This is a web-based application that allows you to: Store and organize surface measurements, characterize surface topography, analyze contact properties and (if you wish) share your data with collaborators or even publish your datasets. For more information on this site please read the accompanying open access paper.

Digital surface twins

A digital surface twin represents the real-life surface you are measuring, together with its descriptive metadata. If you make multiple measurements on the same real-world surface (even using different techniques), you can collect all the measurements together in a single digital surface twin.

Measurements

For each digital surface twin, you must upload one or more measurements. These represent each individual measurement you performed. You can save metadata for each one, and perform basic pre-analysis.

Analysis workflows

A number of analysis workflows, such as computing the power-spectral density or the real area of contact, are performed on-demand on all uploaded measurements. Multiple analyses can be averaged to create, for example, the joint power-spectral density of a digital surface twin.

Sharing & publishing

Digital surface twins can be shared with others for collaboration. You decide whether your collaborators can modify them or not.

Digital surface twins can also be published to make them citable and accessible for everyone.
