Abstract: Based on the tool of the ANSYS Workbench software, the modeling of three-dimensional Entity, meshing and dealing of loads and constraints has been done on the pipelayer’boom. According to the finite element analysis of pipelayer’boom in three basic conditions by the parameter of width, height and thickness, the material consumption of making boom is significantly reduced. All this is done in the premise of ensuring the safety of pipelayer’ boom with the objective of minimizing the quality by the finite element optimization. And the results will be the theoretical basis of the design and improvement of Pipelayer’ boom.

Abstract: In this study, the digital image correlation method(with Newton-Raphson iteration method) is used to measure the in-plane deformation of poly-crystal aluminum. When the specimen is exerted a tensile load, the strain distribution of the specimen surface will be inhomogeneous. The micro-deformation of the poly-crystal aluminum is studied under a SEM(scanning electron microscope), a series of images of the micro crystal are captured during the loading process. By using digital image correlation to analyze the images, the displacement and strain of a micro-crystal are obtained, which provide important data for further analysis of the inhomogeneous properties of the poly-crystal aluminum.
