CheFEM 3 is a specialized software tool developed by Composite Analytica to facilitate the analysis of chemical exposure in polymer-based composite materials. Designed for use in industries such as aerospace, automotive, and chemical processing, CheFEM 3 aims to improve the durability and performance of composites in chemically harsh environments. By replacing traditional, costly, and environmentally impactful experimental methods with advanced computational modeling, CheFEM 3 streamlines the process of predicting material behavior under chemical stress, offering a more efficient and sustainable approach to ensuring the long-term reliability of composite materials[1][2].
Principles
editUtilizing calibrated Sanchez-Lacombe Equation of State and, when necessary, other Equations of States (EOSs), CheFEM 3 accurately predicts crucial material properties such as permeability, chemical resistance, and mechanical response[3][4]. CheFEM 3 operates as a standalone application or integrates seamlessly with other FEM packages like Abaqus, Ansys, and SolidWorks, enhancing workflow flexibility.
