Fractography is the study of features examined on fracture surfaces and has historically been investigated via Microscope or SEM. Microscope being used for macro scale analysis and SEM particularly when it is the nano or microstructure that is vital to the analysis. Both ultimately allowing for the identification of the fracture mechanism type. Although effective, the Microscope clearly has its limitations and the SEM in most cases, other than atomic level analysis, is unpractical for fracture surface measurement and lacks broad use.
The ability of a material to resist cracking, or fracture, has been vital to the studies of fracture mechanics. Until recently the study of fracture toughness has been analyzed at a macro range using powerful instrumentation applied to large samples.
INM – Leibniz Institute for New Materials, Saarbrücken, is a basic and applied research institute in transition to new scientific fields. It has approximately 180 employees, excellent research equipment, and is well supported by public and third-party funding. Its traditional focus is chemical nanotechnology, where the institute holds key patents and has close international links to industry. Under new leadership, this focus is now expanding to include promising novel aspects of materials science, physics and biology.
In this Tech Brief, we present two interesting fluid-structure interaction problems involving adaptive meshing and physical instability
Lately I began to wonder why I hadn't learned how to calculate the beam shear stiffness in college. I vaguely recalled that the teacher told us the shear stiffness could be omitted in the beam calculation compared to the bending stiffness.
Can anybody show me how to calculate the shear stiffness if it is large enough and cannot be ignored? Like the example shown in the picture below
The Department of Materials Science and Engineering in the College of Engineering at the University of North Texas (UNT) seeks highly qualified applicants for a postdoctoral researcher position in computational materials modeling. The successful candidate will work on multiscale modeling of defects and microstructures (e.g., dislocations, grain boundaries, etc), and damage and failure of materials to design and evaluate advanced superalloys for aerospace applications, as part of the federally-funded research program in the Institute for Science and Engineering Simulation (ISES).
