Ultrasonic propagation in fractal porous material having rigid frame
(X ECCOMAS Thematic Conference on Smart Structures and Materials, 2023-07-03)
This paper discusses the impact of the fractal structure of porous materials on wave
behavior. In addition to commonly used parameters such as porosity, tortuosity, viscous and
thermal characteristic lengths, a fractal ...
Thermal properties and pressure-dependent elastic constants of cadmium stannate as a substrate for MEMS: An ab initio study
(North-Holland, 2023-02-15)
Silicon carbide (SiC) has become a suitable replacement to silicon as a substrate for manufacture of microelectromechanical systems (MEMS) that operate in harsh environmental conditions, owing to its better mechanical ...
Investigating the Young's modulus of Cu-Al-Be shape memory alloy using a phase diagram, vibration spectroscopy and ultrasonic waves
(Elsevier, 2024-03-05)
This work presents a method for determining the effective Young’s modulus (Eeffective) and Poisson ratio of small specimens of a ternary shape memory alloy (SMA), Cu-Al-Be. The alloys were synthesized uniformly and ...
