This option decouples the mechanical properties from the beam cross section so you can specify desired mechanical properties without capturing the details of the exact cross section, such as fillet, rounds, chamfers, and tapers. The manually entered stiffness properties must be calculated with ...

The beam cross-section optimization problems have been very important as beams are widely used as efficient load-carrying structural components. Most of the earlier investigations focus on the dimension and shape optimization or on the topology optimization along the axial direction. An important problem...
Pr. 3. A beam with the given cross-section below is made of a material having an allowable tensile stress of (σall)t=105MPa and compressive stress of (σall )c=180MPa. Determine the maximum allowable moment M that can be applied...

Figure 1.JEOL Cross-section polisher. The ion beam irradiates the area protruding from the mask and created a pristine and polished crosssection. The problems associated with conventional polishing can be eliminated with the use of the broad argon ion beam, which also enables larger specimens to...
Ion Beam Cross-section Polishing (CP), is used for revealing sample cross-sections by way of ion beam. Unlike the general CP, CP is capable of eliminating stress effects resulting from the polishing process. Semi-Automated Grinding Polishing Successfully Thin Silicon Substrate to Easily Identify ...
A simple approach for cross-section reconstruction with a fan-beam scanning geometry is discussed. The scanner and the radiation beams are set up in such a way that the projection data can be rearranged and considered as if they were generated from the conventional parallel-beam configuration. Th...
摘要: A method of preparing a TEM sample. A focused ion beam is used to deposit- a mask on the material to be sampled. Reactive ion etching removes material not protected by the mask, leaving a wall thin enough to be imaged by TEM....
