Can we predict the maximum compressive stress of material by knowing the thickness and maximum tensile stress of a bar? Really need some help, thanks for read

Material Properties: Obtain the material's Young's modulus (E) and yield strength (σ_y). These properties are crucial for stress analysis. Stress-Strain Relationship: Use the relationship between stress (σ) and strain (ε) given by Hooke's Law for elastic materials: $$\sigma = E \cdot \epsilon$$ Maximum Tensile Stress: If the maximum tensile stress (σmax) is known, you can use it to find the maximum strain (εmax) using: $$\epsilon{max} = \frac{\sigma{max}}{E}$$ Compressive Stress: For many materials, the compressive strength is higher than the tensile strength. If the material behaves similarly in compression, you can estimate the maximum compressive stress (σc) using the same Young's modulus: $$\sigma_c = E \cdot \epsilon{max}$$ Safety Factors: Always consider safety factors and material-specific properties, as real-world conditions may vary.
The copilot answered: Predicting the maximum compressive stress of a material based on its thickness and maximum tensile stress involves understanding the material's properties and applying relevant stress-strain relationships. Here's a simplified approach:
