Pressing ahead: Unveiling material insights through dynamic nano-indentation - Episode Banner - 2:1 Aspect

Nano-indentation is a powerful surface characterization technique used to probe the mechanical properties of materials. In this webinar, learn how new, dynamic nano-indentation methods are unlocking more advanced measurements such as viscoelastic properties, stress / strain, and continuous depth profiling.

You’ll Learn:

  1. What is nano-indentation and how does it work? How does dynamic nano-indentation differ? 
  2. What kinds of measurements are unique to dynamic nano-indentation (Sinus mode)? 
  3. What are typical applications of Sinus mode measurements? What mechanical properties does it assess? 
  4. How versatile is Sinus mode? 
  5. What kind of materials are suitable for dynamic nano-indentation testing? 

Dynamic Indentation Facilitates Deeper Insights

Nano-indentation has long been an ideal method for mechanical testing of films, coatings, and irregular surface geometries. It achieves nanoscale analysis through a combination of high force resolution with precise measurement of penetration depth. In traditional, quasi-static indentation experiments, one can readily analyze a material’s hardness and elastic modulus.

This, however, only begins to scratch the surface of what nano-indentation can do! Our partner Anton Paar has developed a dynamic testing method called Sinus Mode that applies an oscillatory load in addition to the quasi-static load while reading the dynamic response of the material. In this episode, we’ll be covering some background on the theory of Sinus Mode, and exploring applications and case studies that showcase the power of this technique on Covalent’s UNHT3 Nanoindenter system from Anton Paar.
