Curved Composite Tubes: Stress-Strain Behavior Analysis and Design

Abstract

This paper studies a computational and experimental method for stress-strain analysis and selection of efficient design for composite curved tubes. A finite element-based design model is developed. The paper presents the strength calculation results as well as compares the properties of curved tubes with different reinforcement patterns produced from various materials.
