Structural integrity of components containing fluids is critical for economic, environmental and safety issues. Any risk of catastrophic failure, in the form of either brittle or ductile manner, is not acceptable across the industries. Consequently, many efforts have been invested in the structural integrity aspect to improve the assessment methodologies. One of the ways to aid the decision whether...
In this paper an experimental and numerical work is reported concerning the process of perforation of thin steel plates using different projectile nose shapes. The main goal is to analyze how the projectile shape may change the ballistic properties of materials. A wide range of impact velocities from 35 to 180 m/s has been covered during the tests. All the projectiles were 13 mm in diameter and the...
As we know, expendable prognostic cell, such as "canary" and fuse, is a kind of method that can be applied for prognostics, and it fails earlier than the host product, which provides advance warning of failure. In this paper, a prognostic cell was proposed for electromigration (EM) failure of integrated circuit(IC), and it is composed of stress and detection module, two-stage low gain amplifier,...
This paper presents finite element modelling of the deformation of a detached living cell subjected to microinjection and through the simulation, an investigation of the material properties of the cell components. The model is verified using images of the deformed cell as well as the measured penetration forces in the tests reported in open literature. It is hoped that the modelling in this context...
