Software:CheFEM
CheFEM is a computational software package developed by Composite Analytica for analyzing the effects of chemical exposure on polymers and their composites. It employs the Calibrated Sanchez-Lacombe Equation of States (Chemical) and Finite Element Methodology (FEM) to quantify the impact of chemical exposure on various properties of polymer based materials[1][2].
Overview
Properties such as permeability, chemical resistance, and mechanical response play a crucial role in the performance and service life of polymer-based applications. CheFEM aims to provide engineers and researchers with accurate predictions of these properties, enabling them to assess and evaluate the behavior of polymer materials under different chemical exposures[3].
Features
CheFEM offers a range of features and capabilities to support the analysis of chemical exposure effects on polymers and composites, including:
- Calibrated Sanchez-Lacombe Equation of States: CheFEM utilizes this equation of states to model the behavior of polymers under chemical exposure. The equation helps in predicting thermodynamic and transport properties of the materials[4].
- Finite Element Methodology: CheFEM applies 8-node FEM techniques to simulate and analyze the mechanical response of polymer materials when subjected to chemical exposure. This enables prediction of mechanical properties, such as stress-strain behavior, deformation, and failure mechanisms[5].
- Integration with FEM Packages: CheFEM can be seamlessly integrated as a "chemical exposure plug-in" to widely used mechanically oriented FEM packages, such as Abaqus and Ansys. This integration enables users to combine chemical exposure analysis capabilities with their existing FEM simulations and workflows.
Benefits
- Accurate Property Predictions: By utilizing the capabilities of CheFEM, engineers and researchers can enhance their decision-making process when it comes to choosing and designing polymer materials, leading to more precise property predictions. This software enables accurate forecasts of various properties, such as permeability, chemical resistance, and mechanical response. As a result, it greatly assists in the assessment and optimization of applications that involve polymers.
- Efficient Assessment and Testing: CheFEM allows professionals to digitize their assessment and testing procedures, saving time and resources. By simulating the behavior of polymers under various chemical exposures, it reduces the reliance on physical experiments and facilitates virtual testing and analysis.
Availability
CheFEM is available as a standalone software tool that can be installed on compatible systems (PWA). For integration with FEM packages like Abaqus and Ansys, CheFEM can be utilized as a chemical exposure plug-in.
