USE OF COMPUTATIONAL TOOLS TO ENHANCE THE STUDY OF MICRO- AND MACROMECHANICS BEHAVIOR OF COMPOSITE LAMINA AND LAMINATE IN THE MECHANICS OF COMPOSITE MATERIALS COURSE

Abstract

This paper presents the outcomes of an innovative learning experience in the field of composite materials mechanics at the undergraduate level. The primary objective is to develop a tool that serves as a learning aid, allowing students to focus more on the fundamental concepts behind problems rather than being overwhelmed by complex equations and lengthy arithmetic operations. Utilizing Microsoft Excel, a specialized calculator was developed to handle intricate calculations involved in micromechanics and macromechanics of composite lamina and laminates. The calculator’s accuracy was pre-tested before being deployed to the target students enrolled in the course. Students were then tasked with solving a set of problems both manually and using the calculator to evaluate its efficiency. Results showed that the calculator significantly improved students’ performance, reducing average solution times by nearly 50% for simpler tasks and over 60% for more complex problems. It also proved to be a valuable educational tool, aiding in conceptual understanding and manual calculation verification.
