Crushing stress is a special type of localized compressive stress which occurs at the surface of contact of two members that are relatively at rest. It represents the stress level at which a material begins to deform or fail under compressive loading.
The calculator uses the formula:
Where:
Explanation: The formula calculates the allowable crushing stress by dividing the crushing strength by the product of rivet diameter and plate thickness.
Details: Calculating crushing stress is crucial for determining the structural integrity of riveted joints and ensuring that materials can withstand the applied compressive forces without failure.
Tips: Enter crushing strength in newtons (N), rivet diameter in meters (m), and plate thickness in meters (m). All values must be positive numbers greater than zero.
Q1: What is crushing strength?
A: Crushing strength is the capacity of a material or structure to withstand loads tending to reduce size.
Q2: What are typical rivet diameters?
A: Rivet diameters typically range from 1/16-inch (1.6 mm) to 3/8-inch (9.5 mm), though special sizes up to 8 inches (203 mm) are available.
Q3: How does plate thickness affect crushing stress?
A: Thicker plates distribute the crushing force over a larger area, resulting in lower crushing stress for the same applied force.
Q4: When is this calculation most important?
A: This calculation is particularly important in structural engineering, mechanical design, and any application where riveted joints are subjected to compressive loads.
Q5: What units should be used for input values?
A: For consistent results, use newtons (N) for crushing strength and meters (m) for both rivet diameter and plate thickness.
