Your role
Background
Adhesive bonding plays a pivotal role in various engineering applications, from aerospace structures to automotive manufacturing. Understanding the mechanical behavior of adhesive joints is crucial for ensuring the structural integrity and durability of bonded assemblies. This thesis aims to develop a comprehensive methodology for evaluating adhesive performance utilizing Cohesive Zone Modeling (CZM) within the Finite Element Method (FEM) framework.
Description of the master thesis
The proposed methodology involves the following key steps:
- Literature Review: A thorough review of existing literature on adhesive bonding, CZM, and FEM techniques to establish a comprehensive understanding of the current state-of-the-art methodologies and challenges.
- Material Characterization: Experimental characterization of adhesive material properties, including fracture toughness, cohesive strength, and other relevant parameters, to accurately represent the adhesive behavior in numerical simulations.
- CZM Implementation: Development and implementation of CZM within FEM software (primarily Ansys and LS-DYNA), including defining cohesive laws that govern the behavior of adhesive interfaces under various loading conditions.
- Numerical Simulations: Conducting numerical simulations of adhesive joints using the developed CZM approach to predict their mechanical response under different loading scenarios, such as tension, shear, and peel.
- Validation: Validation of the developed methodology through comparison with experimental data and existing analytical models to ensure its accuracy and reliability.
- Case Studies: Application of the methodology to real-world adhesive bonding scenarios, such as composite-to-metal joints or multi-material assemblies, to demonstrate its practical utility and effectiveness.
Your profile
The outcome of this thesis will be a robust methodology for evaluating adhesive performance using CZM within the FEM environment. This methodology will enable engineers to predict the mechanical behavior of adhesive joints more accurately, optimize bonding processes, and design structures with improved reliability and durability. Moreover, it will contribute to advancing the state-of-the-art in adhesive bonding technology, benefiting industries ranging from aerospace and automotive to civil engineering and beyond.
