What's New in Mohr's Circle

Bug fixes and other minor updates.

User reviews

Crashes

The app is unable to cope with 0 shear stress and crashes instantly,

An obvious thing to have tested, so consequently you can't have much confidence in the rest of the app.

Decent

Would like to be able to rotate the stress block to calculate the stresses on a plane inclined from the horizontal. Otherwise very handy.

Lacking

So this app definitely needs more input fields... The only inputs are sigma x and sigma y, which only through trial and error did I figure out was sigma n (normal stress) and sigma s shear stress. In addition there was a field T(x,y). One of the primary use cases of a mohr circle is to find those sigma x and sigma y, so this is kinda backwards for that. Ui design and aesthetics are top notch however. I'll add stars when this app becomes useful.

***update: Please, add support for coulomb failure envelope. And also please add a parameter for pore pressure, making this useful for structural geology.

Perfect

Great tool, great app! Shows result in 4 nice graphical views as well as a table for easy reference. Saves information as states for easy lookup later.
