Continuous Dynamic Analysis (CDA) Option Continuous Dynamic Analysis (CDA) Dynamic studies of compliant fibers Dynamic studies of biological materials Dynamic studies of polymers and composites Until recently, accurately determining dynamic properties for specimens at the nanoscale has been limited to fixed-strain investigations — posing significant technical challenges for improving the understanding of material behavior. The Continuous Dynamic Analysis (CDA) option on the T150 UTM The state-of-the-art Keysight T150 UTM enables researchers to provides a simple means of determining dynamic properties, understand dynamic properties of compliant fibers via a large such as storage and loss modulus and tan d. This option utilizes dynamic range in the industry and the high resolution on the a technique whereby a nanomechanical actuating transducer market (fi ve orders of magnitude of storage and loss modulus). head superimposes a high frequency oscillatory force onto the It also lets researchers investigate tension/compression nominal force. The amplitude of the oscillation is measured by properties of biological materials via the CDA option. a capacitive sensor that is integrated into the nanomechanical actuating transducer head. The CDA option can measure T150 advantages include fast, accurate generation of real-time complex moduli over a range of frequencies. test results, understanding of strain-rate-sensitive materials The CDA option offers a direct, accurate measurement of the sampling in biomaterials applications. and time-dependent response, and improved statistical specimen’s stiff ness at each point in the experiment, enabling mechanical properties to be determined continuously as the specimen is strained. By measuring both the amplitude and phase relationships between the load and displacement oscillations, the CDA option makes it possible to determine storage and loss modulus. The option enables T150 UTM users to gain access to dynamic properties information continuously throughout the force curve, providing a wealth of information on the material’s response. Features and Benefits + Allows mechanical properties of the specimen to be determined continuously as specimen is strained Allows complex moduli to be measured at various preload values over a range of strain Operates over a range of frequencies, allowing better understanding of viscoelastic response of materials Figure 1.

Figure 2. The T150 UTM system with the CDA option imposes a small oscillation on material that is being simultaneously subjected to a variable quasi-static strain, thereby providing material properties over a range of strain in one experiment CDA Option specifications Force amplitude range: 0.1μN to 4.5mN Frequency range characterization of instrument dynamic response (sample dependent): 0.01Hz to 200Hz Maintaining system productivity is an integral part of KLA’s yield optimization solution. Eff orts in this area include system maintenance, global supply chain management, cost reduction and...
