Factor of safety for brittle materials Solution

STEP 0: Pre-Calculation Summary

Formula Used

Factor of Safety = Ultimate Tensile Strength/Allowable Stress for Static Load
f_s = S_ut/σ_al
This formula uses 3 Variables

Variables Used

Factor of Safety - Factor of Safety expresses how much stronger a system is than it needs to be for an intended load.
Ultimate Tensile Strength - (Measured in Pascal) - Ultimate Tensile Strength (UTS) is the maximum stress that a material can withstand while being stretched or pulled.
Allowable Stress for Static Load - (Measured in Pascal) - Allowable Stress for Static Load is also known as working load and is the ratio of tensile strength and factor of safety.

STEP 1: Convert Input(s) to Base Unit

Ultimate Tensile Strength: 122 Newton per Square Millimeter --> 122000000 Pascal (Check conversion here)
Allowable Stress for Static Load: 45 Newton per Square Millimeter --> 45000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_s = S_ut/σ_al --> 122000000/45000000

Evaluating ... ...

f_s = 2.71111111111111

STEP 3: Convert Result to Output's Unit

2.71111111111111 --> No Conversion Required

FINAL ANSWER

2.71111111111111 ≈ 2.711111 <-- Factor of Safety

What is factor of safety and why is it required?

There are always approximations in engineering calculations. Hence, the allowed stress is kept less than failure stress, and the ratio of failure stress to allowed stress is called factor of safety.

How to Calculate Factor of safety for brittle materials?

Factor of safety for brittle materials calculator uses Factor of Safety = Ultimate Tensile Strength/Allowable Stress for Static Load to calculate the Factor of Safety, The Factor of safety for brittle materials formula is defined as the ratio of ultimate tensile strength and allowable stress. It is the required margin of safety for a structure or component according to code, law, or design requirements. In this case, the failure stress is equal to tensile yield stress. Factor of Safety is denoted by f_s symbol.

How to calculate Factor of safety for brittle materials using this online calculator? To use this online calculator for Factor of safety for brittle materials, enter Ultimate Tensile Strength (S_ut) & Allowable Stress for Static Load (σ_al) and hit the calculate button. Here is how the Factor of safety for brittle materials calculation can be explained with given input values -> 2.711111 = 122000000/45000000.
