SHANG, Wei; YANG, Xiaojing  e  ZHANG, Lina. Study of anisotropic mechanical properties for aeronautical PMMA. Lat. Am. j. solids struct. [online]. 2014, vol.11, n.10, pp.1777-1790. ISSN 1679-7825.  http://dx.doi.org/10.1590/S1679-78252014001000005.

For the properties of polymer are relative to its structure, the main purpose of the present work is to investigate the mechanical properties of the aeronautical PMMA which has been treated by the directional tensile technology. Isodyne images reveal the stress state in directional PMMA. And then, an anisotropic mechanical model is established. Furthermore, all mechanical parameters are measured by the digital image correlation method. Finally, based on the anisotropic mechanical model and mechanical parameters, the FEM numerical simulation and experimental methods are applied to analyze the fracture mechanical properties along different directions.

Palavras-chave : aeronautical PMMA; isodyne method; digital image correlation method; anisotropy; fracture.
