This video will take you through how to evaluate the fatigue failure and the fatigue analysis methods, high cycle fatigue, low cycle fatigue, stress life fatigue analysis, strain life fatigue analysis, fracture mechanics, SN curve for structural steel, Alternating stress vs Number of cycles, What is fatigue life, fatigue damage, Fatigue Safety Factor, Bi Axiality, Sensitivity Curve, What are the Mean Stress correction Theory, Goodman equation in Fatigue analysis, Von Mises Stress approach for fatigue analysis, Fatigue Strength Correction Factor

How to decide whether fatigue analysis is required
01. Component/structure type: Consider if the component experiences cyclic loading or repeated stress.
02. Loading conditions: Assess if the component is subjected to fluctuating or cyclic loads.
03. Material properties: Evaluate the susceptibility of the material to fatigue failure.
04. Operational lifespan: Determine if the component is expected to endure a large number of load cycles.
05. Safety criticality: Consider if the failure of the component could have severe consequences.
06. Regulatory requirements: Check if specific industry regulations or standards mandate fatigue analysis.
07. Past failures/known issues: Consider any previous fatigue failures or known fatigue-related problems.

Where/How to get the fatigue curve or SN curve of specific material
01. Experimental Testing: Conducting fatigue tests on specific materials or components provides real-world data to generate fatigue curves. These tests involve subjecting the material or component to cyclic loading under controlled conditions while measuring the number of cycles to failure.
02. Material Standards and Specifications: Many engineering materials have established standards or specifications that include fatigue data. These documents often provide S-N curves for different materials, including metals, composites, and polymers. Standards organizations such as ASTM, ISO, and SAE publish these standards.
03. Materials Databases: Several databases compile fatigue data from various sources, including experimental studies and research papers. These databases may require a subscription or membership for access. Examples include the NIST Materials Data Repository, the MatWeb database, and the Fatigue Data Handbook.
04. Published Research: Research papers, technical journals, and conference proceedings often present fatigue test results and S-N curves for specific materials or components. These publications can be found through academic databases, online libraries, or by directly contacting researchers in the field.
05. Industry Guidelines and Handbooks: Certain industries have guidelines or handbooks that provide fatigue curves specific to their applications. For example, the American Institute of Steel Construction (AISC) provides fatigue design guidance for steel structures, including S-N curves for various steel grades.

BEST TUTORIAL FOR FATIGUE ANALYSIS EVER..!!
Thanks a lot for sharing..!! much appreciated.

[theflashleopard]

Extremely good insight.
But with all due respect Sir, please be a little more quick I had to watch entire video at a playback speed of 1.75.
Otherwise good content.

[mschandra]

Thanks for the video.

Could you please create a video for LCF analysis, with complete theoretical approach considering any steel.

[naveenn.g]

thank you to CAE world wide, its very easy to understand fatigue concepts and great explanation by the narrator.

[amitchauhan]

One of the best tutorial I ever had...Thank You V. Much.... and please if you could upload more videos on fatigue...i.e. Low Cycle Fatigue for Circular Bar section (ASTM E606).

[SSCENGINEERS]

thanks sir to clear all doubts. You are amazing

[vinaykumarsambalmath]

Extremely informative video on fatigue loading! Thankyou for bringing this..
Can i please know which Software is this in detail?
Please reply at the earliest because I need this for my project work

[Rohit_rennfahrer]

can you please upload a video on fatigue analysis of helical spring and also tell how we define S-n curve for that.

[harrisiqbal]

Didn't quite understand the Biaxiality Contour Plot but excellent video
