The main objective of this paper is to investigate a way to characterize experimentally the mechanical behavior of low modulus adhesives. In this context, the relaxation and complex moluli master curves of a SIKAFLEX 505 adhesive are obtained by means of dynamic mechanical thermal analysis. Firstly...
The nominal stress and strain of the samples can be obtained directly from the stress-strain curve, the modulus (stiffness) is the slope of the stress-strain curve when the strain is 5%, and the fracture work (toughness) is the area enclosed by it. The reversibility of the hydrogels is ...
Since the pile deformation by the excitation force during the LSPIT is small, the material parameters, Young’s modulus, and density changes are also small. Therefore, the time-domain curve of foundation pile vibration velocity is directly related to the pile geometry [30]. Typical pile foundati...
For numerical modelling and additive manufacturing, VeroWhite (Young modulus \(E = 1.6\,{\text{GPa}}\), mass density \(\rho = 1174\,{\text{kg/m}}^{3}\) and Poisson’s ratio \(\nu = 0.33\)) Stratasys Ltd is used. Subsequently dynamic mechanical test is performed to determine the...
Evaluation of two different OSG films revealed significant differences in Young's modulus and residual stress between the two dielectric films. Young's modulus of both types of OSGs was independently measured using nanoindentation and found to be at least 8.5-17% greater than that measured using ...

Then, the effect of temperature on the ultrasonic velocity essentially reflects its effect on Young’s modulus. The microscopic analysis of Young’s modulus shows that the reaction of a solid to all forces comes from the potential energy of the interaction between atoms. The interaction potential ...
s open pores and resulted in densification by liquid phase sintering [44,71]. The densification of these pores will increase the solid matter in the matrix of the bars in resisting any applied load to fracture the tiles, consequently increasing its strength against fracture or its modulus of ...
Meanwhile, the plastic deformation induced by indentation can cause the work hardening of the neighboring regions; hence, the indentation depth at the grain boundary is quite different due to the loading sequences [33]. To explore the influence of grain gradient on elastic modulus and hardness, ...
