 Mohr's circle
analysis for plane stress, plane strain, strain rosettes, and moments of inertia
problems is available in MDSolids.
 Normal stresses
in the x and ydirections are specified in terms of either tension or compression stress rather than either a positive or a negative number.
Shear stress is defined as either clockwise or counterclockwise on the xface
of the stress element.
 An orientation
diagram is displayed to show the stresses in the x and ydirections as specified
by the user.
 The points that correspond to the x and yfaces of the
stress element are indicated on the circle.
 Separate pictures are drawn to indicate the orientation of
the principal stresses relative to the xy coordinate system as well as the
maximum shear stress orientation.
 The drawings give
users a clear visual depiction of the various angles in the xy space and the
sigmatau space as well as the directions of rotation in each coordinate system.
 Stresses at any
arbitrary orientation can also be investigated. A drawing surrounded with
a protractorlike border enables the user to obtain stresses at any arbitrary
orientation with merely one mouse click.
 The Mohr's circle
calculations can be accessed from both the beam and torsion member portions
of MDSolids. Data from combined stress situations is automatically supplied
from these routines to the Mohr's circle calculation.
