Stress Concept:
Flexure analysis focuses on the bending behavior of a section subjected to axial loads (forces pulling the section apart). The study aims to predict the bending stress and bending moment experienced by the section.
Strength Concept:
In contrast, strength concept focuses on the overall capacity of a section to resist bending. It determines the minimum shear stress required to cause failure in the section.
Important Points for Analysis:
Type of Sections: Analysis can be applied to various shapes like circular, rectangular, and triangular sections.
Loading Conditions: The analysis takes into account both axial load (P) and moment (M) applied to the section.
Material Properties: The analysis requires knowledge of the material's stress-strain behavior, including its elastic and plastic properties.
Analysis Methods: Several analytical methods exist, including Analytical Solutions (e.g., Euler's Formula), Finite Element Analysis (FEA), and Analytical Models.
Examples:
Analyze a circular section subjected to an axial load.
Calculate the bending stress and strain of a rectangular section under a bending moment.
Apply FEA to a steel beam subjected to bending loads to predict its behavior.
Further Insights:
The analysis involves applying principles of mechanics, geometry, and thermodynamics.
It requires a good understanding of mathematical principles like stress, strain, and equilibrium equations.
Various computer-aided design (CAD) software tools can be used for the analysis
