Ultrasonic testing is an important tool for assessing the structural integrity of pressurised components in nuclear power plants during in-service inspection. Consequently, the reliability of inspection is of high significance. In particular, it is i

Scratch resistance (SR) of externally plasticized hydroxypropyl methylcellulose (HPMC) films intended for tablet film coatings was studied. Special attention was paid to effects of short-term aging and ultraviolet (UV) treatment on the SR properties

Consolidation mechanisms for colloidal suspensions are currently inadequately characterized due to lack of suitable experimental techniques. We contributed to this question by combining ultrasonic and optical measurements. White light specular and di

We want to understand where wood strength comes from in order to artificially engineer the mechanical properties of wood. This study aims to measure the effect of macroscopic stress on micro scale modulus of elasticity of Scots pine (Pinus Sylvestris

The mechanical properties of a silicone tube blood vessel phantom (outer radius 4.04±0.04 mm and wall thickness 1.00±0.02 mm) carrying in‐plane ultrasound wave propagation, was studied as function of applied axial tension. A 23 kHz, 1‐cycle squ

We combined noninvasive ultrasonic and optical measurements to estimate the mechanical properties of forming colloidal films. Light reflection measurements determined the stage of drying and film structure. A concurrent ultrasound measurement quantif
