PROFILE: Stress concentration elimination software.

For a desired profile to meet the X and Y dimensions of a corner in a panel and to generate no stress concentration under a single applied loadcase.


The software will provide a tabulated set of x and y coordinates to define the profile form that exhibits no stress concentration, gives a stress reduction distribution and an inverted stress distribution so that the stress reduces towards the base and not increases.


By changing the control width of base (X dimension) and the height (Y dimension) a narrow or wide footprint (aspect ratio) can be achieved yet the profile retains all the characteristics as described above.

L2: Lightweighting - Introduction to the Reduction of Stress Concentrations

A message from the course designer, Dr. Warren Leigh.

I started as a Stress Engineer in 1984 whilst at British Aerospace. Stress concentration reduction is all important throughout all industries. I have researched and developed my own proven methods and used thoroughly over the many years the conventional and advance techniques to reduce or even eliminate the destructive effects of stress concentrations. I have tailored this course to provide extensive but selective information and techniques to the student that I have acquired over the decades since.​

Stress Concentration Reduction and Elimination.

Lightweighting techniques also include the need to reduce Stress Concentrations (Kt) in a product. Because frequently, when designers attempt to reduce high stress concentrations the weight of a product is increased.


Stress concentrations have been shown to encourage surface crack propagation and dictate the probability of fracture occurrence. High stress concentrations, promotes early component failure initiating at the surface of the component. ​90% of crack initiation flaws begin at surface locations and propagate in regions of stress concentrations. 


​A key factor in product life enhancement is the need to reduce stress concentrations. The minimisation of stress concentrations or ideally, elimination of stress concentrations will result in a longer product life.


​Many Designers and Engineers to reduce stress concentrations, will apply a circular fillet and increase the radius of the fillet in an attempt to reduce the stress concentration. However, that increasing the circular fillet radius is not consistent with minimum stress concentration. There exists an optimum circular fillet radius (based on part geometric ratios and loadcase) above or below which will generate a higher value of stress concentration and unnecessarily increase component WEIGHT (Tranxuan, 1994). 


Therefore, its important to be aware of and use the techniques to reduce or even eliminate stress concentrations if you want to obtain a low weight, strong and long life product.


In this course you will learn; about;

-the conventional techniques for Stress Concentration reduction under a single loadcase

-the advanced techniques for Stress Concentration reduction under a single loadcase

-Optimum Stress Concentration reduction techniques under a single loadcase

-Advanced Stress Concentration reduction techniques under multi-axial loadcases

-Simple technique to eliminate Stress Concentrations for any geometric aspect ratio

-How to invert the Stress Distribution in the fillet region, i.e.remove the high stress​​
