Percent elongation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Percent elongation = (Fracture Length-Initial Length)*100/Initial Length
%EL = (l_f-l₀)*100/l₀
This formula uses 3 Variables

Variables Used

Percent elongation - Percent elongation is the percentage of plastic strain at fracture.
Fracture Length - (Measured in Meter) - Fracture length is the length measured subsequent to fracture and after the two broken ends have been repositioned back together.
Initial Length - (Measured in Meter) - Initial Length before the application of load.

STEP 1: Convert Input(s) to Base Unit

Fracture Length: 1.5 Centimeter --> 0.015 Meter (Check conversion here)
Initial Length: 5000 Millimeter --> 5 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

%EL = (l_f-l₀)*100/l₀ --> (0.015-5)*100/5

Evaluating ... ...

%EL = -99.7

STEP 3: Convert Result to Output's Unit

-99.7 --> No Conversion Required

FINAL ANSWER

-99.7 <-- Percent elongation

Fracture toughness

Go Fracture Toughness = Dimensionless Parameter in Fracture Toughness*Applied stress*sqrt(pi*Crack Length)

Critical stress for crack propagation

Go Critical stress = sqrt(2*Young's Modulus*Specific surface energy/(pi*Crack Length))

Percent cold work

Go Percent cold work = 100*(Cross-sectional Area-Area after deformation)/Cross-sectional Area

Percent reduction in area

Go Percent reduction in area = (Cross-sectional Area-Fracture area)*100/Cross-sectional Area

Percent elongation

Go Percent elongation = (Fracture Length-Initial Length)*100/Initial Length

Stress concentration factor

Go Stress Concentration Factor = 2*sqrt(Crack Length/Radius of curvature)

Mean stress of stress cycle (fatigue)

Go Mean Stress of Stress Cycle = (Maximum Tensile Stress+Minimum compressive stress)/2

Maximum stress at crack tip

Go Maximum Stress at Crack Tip = Stress Concentration Factor*Applied stress

Range of stress (fatigue)

Go Range of stress = Maximum Tensile Stress-Minimum compressive stress

Stress ratio (fatigue)

Go Stress ratio = Minimum compressive stress/Maximum Tensile Stress

Modulus of resilience

Go Modulus of Resilience = Yield Strength^2/(2*Young's Modulus)

Stress amplitude (fatigue)

Go Stress Amplitude = Range of stress/2

Percent elongation Formula

Percent elongation = (Fracture Length-Initial Length)*100/Initial Length
%EL = (l_f-l₀)*100/l₀

Ductility and Percent elongation

Ductility can be expressed quantitatively as percent elongation. A significant proportion of the plastic deformation at fracture is confined to the neck region, this magnitude of will depend on specimen gauge length.

How to Calculate Percent elongation?

Percent elongation calculator uses Percent elongation = (Fracture Length-Initial Length)*100/Initial Length to calculate the Percent elongation, Percent elongation is the percentage of plastic strain at the fracture. Percent elongation is denoted by %EL symbol.
