phys.mtrl is GUI Workbench for performing Mechanics of Materials calculations.

• Python 3
• tkinter
• numpy
• sympy
• matplotlib

Here is a summary of some of the currently implemented features.

• File Save and Open: human-readable xml files are used to store the current state of the lab to be loaded later
• View
  • Set the scale of the lab
  • Hide or show each toolbar
• Options
  • Toggle weightless members
  • Options for snapping the location and angle of supports
• Simple interface for placing members of several cross sections and materials and placing supports and loads (point or distributed) on those members

• Mass Properties: Report mass, volume, and several other values related to the member and its material
• Static Equilibrium: Recursively calculates all the reaction forces in the structure, then reports the reaction forces from the supports and joints on the selected member
• Axial Stress and Strain: Reports the stress and strain caused only by axial forces (compression and tension) on the member
• Shear and Moment: Plots Shear and Moment along the length of a beam
• Axial and Shear Stress: Plots Axial and Shear stresses at every point in the profile of the member, based on axial forces combined with bending. Also calculates the principle stresses and identifies max and min values
• Euler Buckling: Reports if the column is stable according to the Euler Buckling theory

• Allow members to be moved after being placed.
• Use equations for elongation to deal with statically indeterminate members.
• Add applied torques.
• Add an option for snap to grid when placing everything.
• Add more options for cross section and material.
  • Upload some database of materials and material properties.
• Fix the mohr_transform function so it works fine with symbolic functions, then use that to find the max and min symbolically in the sig_tau report.
• Make it so that the max2d_grad function works better with piecewise.
• Add keyboard shortcuts
