FMAX: Maximum principal force per unit length acting at the midsurface of

the element. Note that by definition, principal forces are oriented such

that the associated shearing force per unit length is zero.

FMIN: Minimum principal force per unit length acting at the midsurface of

the element. Note that by definition, principal forces are oriented such

that the associated shearing force per unit length is zero.

VMAX: Maximum principal shear per unit length acting at the midsurface

of the element. Note that by definition, principal shears are oriented on

faces of the element such that the associated shears per unit length on

perpendicular faces are zero.
