Having trouble figuring out how to link the two Young's Moduli to the Bending Moment, any suggestions?
Take a look at the slides in this lecture on the bending of composite beams:AdamMcParland said:
Here is a copy of an exchange about a similar situation in another engineering forum.AdamMcParland said:
A composite beam is a structural element composed of two or more different materials, typically a combination of steel, concrete, and/or timber. Stress in a composite beam occurs when external forces, such as loads or weight, are applied to the beam, causing it to bend or deform.
There are several factors that can contribute to stress in a composite beam, including the type and magnitude of the applied load, the properties and dimensions of the materials used, and the geometry of the beam itself. Other factors such as temperature changes, moisture levels, and design flaws can also impact stress levels.
The stress in a composite beam can be calculated using the principles of mechanics and structural analysis. This involves considering the distribution of external loads, the properties of the materials, and the geometry of the beam. Advanced computer modeling and simulation techniques can also be used to accurately calculate stress levels in composite beams.
There are several ways to manage stress in a composite beam, including selecting appropriate materials with high strength and stiffness, optimizing the beam's design and dimensions, and implementing reinforcement or support structures. Regular inspections, maintenance, and repairs can also help prevent excessive stress levels in a composite beam.
Excessive stress in a composite beam can lead to several negative consequences, including structural failure, collapse, and safety hazards. It can also cause cracks, deformations, and other forms of damage that can compromise the integrity and functionality of the beam. Therefore, it is important to carefully consider and manage stress levels in composite beams to ensure their structural stability and longevity.
