Product Option for Nano Indenter ® G200 Continuous Stiffness Measurement (CSM) Overview and biomedical materials. The Nano Indenter G200 equipped Nanoindenters are accurate, flexible, user-friendly instruments with the CSM option can fully characterize dynamic properties for nanoscale mechanical testing. Electromagnetic actuation like strain rate sensitivity with nanometer precision. It can also allows Nanoindenters to achieve high dynamic range in force provide values such as complex (dynamic) modulus for and displacement. These instruments enable users to measure viscoelastic materials that exhibit a phase difference between Young’s modulus and hardness in compliance with ISO 14577 stress and strain. Indentation tests using the CSM option can standards and deformation over six orders of magnitude, from be controlled with a constant strain rate, a critical test mode for material systems such as pure metals or low melting point The accuracy and reliability of the results of nanoindentation testing depend on more than knowledge of the tip geometry and analysis of force vs. displacement curves. To accurately calculate mechanical property values, the contact area and stiffness of the contact between the indenter tip and the sample material must also be accurately determined. Nanoindenters from KLA characterize mechanical properties such as modulus of elasticity, loss factor, and fracture behavior with nanometerrange precision, using both quasi-static and dynamic depthsensing indentation methods. Quasi-Static and Dynamic Methods for alloys, polymer films and film/substrate systems. Features and Benefits ++ Accurate, repeatable results conforming to ISO 14577 standards ++ Dynamic properties characterization via continuous measurement of stiffness ++ Seamless compatibility with Nano Indenter XP and DCM indentation heads ++ Full characterization of dynamic properties with nanometer-range precision Nanomechanical Characterization ++ Accurate characterization of viscoelastic materials In conventional quasi-static indentation testing, contact ++ Ability to control indentation tests with a constant strain rate stiffness is determined by analyzing the force vs. displacement curve during unloading. This method provides a single result for a given indentation depth. The Continuous Stiffness Measurement (CSM) technique, compatible with both the XP Applications ++ Semiconductor, thin films, MEMS (wafer applications) and the DCM II indentation heads, satisfies application ++ Hard coatings, diamond-like carbon (DLC) films requirements that must take into account dynamic effects, ++ Composite materials, fibers, polymers such as strain rate and frequency. The CSM option offers a means of separating the in-phase and out-of-phase components of the load-displacement history. Phase separation enables accurate determination of the location of initial surface contact, and continuous measurement of contact stiffness as a function of depth or frequency, eliminating the need for unloading cycles. The CSM option is applicable for not only stiff materials such as metals, alloys and ceramics, but also for materials with compliant material properties, such as polymers, structural composites ++ Metals, ceramics ++ Biomaterials
