a 3D finite element model of a typical screw type blind rivet was built and validated by experimental results. According to the simulation results, it was found that the large blind head’s shape and pre-load were highly sensitive to the thickness ratio of insert and sleeve, the height ratio...
while cracks and pores lowered the stiffness. The results suggest a declining trend with increasing maturity for elastic modulus, with no apparent relationship with thermal maturity for hardness. The study demonstrates a multimethod approach for fast and reliable assessment of representative material parame...
Together with increasing thermal conductivity, mechanical characteristic like hardness of TIM should not be very high as it can cease the workability (flow state which is essential to fill the micro-gaps) of PCM during transition regime. To keep the workability, filler concentration needs to be ...
This analytical process is a crucial research and characterization method for evaluating clinker quality in materials science and the construction industry. By studying the microstructure, researchers can gain insights into the composition of phases, the presence of impurities, and the overall quality of...
Figure 12A displays the outcomes of the impact experiments, whereas Figure 12B displays the results of the Vickers micro-hardness testing. The mean Charpy impact strength (measured in kJ/m2) and Vickers micro-hardness (measured in HV) for all the materials inspected were assessed to take into ...
When experts push the boundaries of science, that’s when new discoveries are made. Today’s Timken customers are getting closer to makingelectric flight a realityand findingnew waysto harness renewable energy. Every mechanical leap forward relies on a common question: which materials can manage th...
“This is important because any attempt to give an insight into the mechanism that improves a material’s property, especially hardness, is technologically extremely significant,” she toldNew Scientist. The more that is understood about what influences the hardness of materials, the more it will ...
Many researchers around the globe pay attention to the polymer nanocomposite material (organic–inorganic) due to their unique property such as increases flexibility, improved surface hardness and heat resistance (due to inorganic components)8,9,10,13,14,15. Yang et al.16 have reported the ...
However, because of the different dependence of domain-wall pinning and dislocation pinning on defect size, magnetic and mechanical hardness are not always concurrent. For example, solid-solution alloying elements in iron or nickel can produce mechanical hardening without producing magnetic hardening. An...
Vandana Soni, in Journal of Drug Delivery Science and Technology, 2020 6.1.2.1 Films/coatings Silk has been also worked as a potential and budding aqueous film coating agent for drug carriers. The SF films provide the controlled release for drug to enhance and improve the delivery of bioacti...
