Matlab Progress 5




Mohr circle :

By this program, you can draw Mohr circle and the Maximum shearing stress through inserting the normal stresses in the x-direction, the y-direction, and shearing stress.

 
Hint:

You need to (Circle .m) to operate the (Mohr circle .m) as it’s just function. For inserting data, the direction of shearing stress (its sign is positive at clockwise and is negative at anticlockwise) .

Matlab Progress 4 



In this term, we change our knowledge about MATLAB (GUI) seeking to get the best away to reach the correct answer and updating the solving methods in the previous term. Through this term, we changed the design from 2 to 3 times to get the stylist form to attract the User to access his desired answer.

What happened in this term?

We divide the beams to two types:
  • Simply supported beam
  • Cantilever beam
With our problem, you can calculate:
  • Reaction.
  • Number of moments, disturbed loads, and external concentrated loads.
  • Drawing Shear –bending moment diagram (to get any data at any distance!!)
  • Maximum stress.

The initial design  - click to enlarge


In addition to the previous required, we can get:
  • Vertical shear.
  • Horizontal shear.
  • Bending moment.
  • Stress at any distance.

What we updated in this term?

By collecting information and data about the ADVABCED MATLAB!!!
We can update:
  • Centroid 
  • Centroid Moment of inertia. 
  • Calculating the first moment of area.
Note : the Program will be released here within days, Thanks for your patience.

"Bending Program"



This part of the program deals with a new chapter which is the bending, in this part we can calculate the stresses at any point in the cross section area, we are trying to calculate the stress in many different cross section areas, the program calculates the stress by getting firstly the moment of area of the shape (moment of inertia) around its centroid and then by giving it the moment that act on the shape, the program then get the stress, Not only it can get the stress on the shape but also the moment on it if the stress is given. The program can calculated the centroid and the moment of area of the shape if it is not easy to be obtained by the user. Not only the bending happen by moment but also forces can bend shapes, the program can solve also these problems.

This is the part that doesn’t calculate the centroid of the shape because it is easy to be obtained by user like this problem:

"Stress & Strain Program"


This post is about chapter 2 which deals with (Stress & Strain) , this part from our program is used to solve the problems of stress & strain by getting the deflection in the rod and also calculate both stress and strain in the rod ,For example  in the following picture the rod is divided into 3 sections according to the forces and the lengths and the areas on each section , For example :


Screenshot of the program :

Press on image for full size


The program can get the deflection &(or) stress , strain  not only in the whole rod but also in each section in the rod.
 
It is clear that the program also solve the problems which are affected by thermal effect which have a great effect on the deflection and also the stain, The program is capable of solving a problem of 5 sections not only three.
 
Finally we can say that it is easy to deal with this program, just to enter the input in the problem and it calculated what do you want, But the main use of this program is to be like a calculator the user must think about the problem and divided it in to sections and know the force and length and area of each section only the program calculate the inputs and get the final answer.

Introduction :

  • Through this page, we will show how is the progress of our project (MATLAB SOLVER), its mission is solving our problems in structure analysis whatever its type (reaction forces, truss, bars, shafts ……etc ;).
  • We need to your help by your attempt in using our solver so as to know the faults within our SOLVER. 
  • We can answer your questions about our solver or about MATLAB (the language technical computing) by notes, references and courses from a vary universities.
