The data acquisition system can also be employed using a sound card of a PC and Matlab software to obtain and analyze Young modulus output signals effectively.
What is the Young’s modulus of Ti-24Nb (ST)?5 answersThe Young’s modulus of Ti-24Nb alloy varies based on processing and composition. Ti-24Nb-4Zr-8Sn alloy exhibits a Young’s modulus ranging from about 50 GPa in the as-built and α″ phase conditions to approximately 75 GPa in α precipitates containing conditions. On the other hand, Ti-24Nb alloy can achieve a minimum Young’s modulus of 52.13 GPa in Ti-30Ta-21Nb composition, showcasing high strength-to-modulus ratios suitable for biomedical applications. Additionally, the Ti–24 mol %Nb–3 mol %Al alloy demonstrates anisotropy in Young’s modulus, with values reaching a minimum along certain crystallographic orientations and varying with temperature. Therefore, the Young’s modulus of Ti-24Nb alloy, particularly Ti-24Nb-4Zr-8Sn and Ti-30Ta-21Nb compositions, can range from around 50 GPa to 75 GPa, influenced by processing, microstructure, and alloying elements.
What is Young Modulus characterization?5 answersYoung's modulus characterization refers to the process of determining the Young's modulus of a material, which is a measure of its stiffness or elasticity. It is an important mechanical property that describes how a material deforms under stress. Several techniques have been proposed for the characterization of Young's modulus in different materials and applications.
One approach involves using a novel in-situ measurement technique for polydimethylsiloxane (PDMS) microfluidic chips. This technique integrates a piezoelectric sheet underneath the chip and monitors the blur and speckle contrast of the pillar to predict the Young's modulus. Another method uses the impulse excitation technique to determine the Young's modulus of Fused Deposition Modeling-printed thermoplastic materials. This non-destructive characterization method uses a test piece's natural frequencies to obtain an effective isotropic Young's modulus.
In the field of microstereolithography, a method has been developed to measure the dynamic response of additively manufactured parts and infer the dynamic modulus of the material in the ultrasonic range. This method involves measuring the wave speed and attenuation of an ultrasonic pulse traveling through the materials.
Furthermore, an inverse approach has been proposed to estimate the frequency-dependent Young's modulus of a viscoelastic polymer layer in a laminated structure. This approach uses a fractional derivative model and Bayesian identification based on measurement and modeling uncertainties.
Overall, Young's modulus characterization involves various techniques and methods tailored to specific materials and applications.
