We have demonstrated that the torsion angle is larger than the actual degree of FA in theory.
We then calculated the single-point energies of the structures; this was obtained by gradually increasing the torsion angle of the selected bond in increments of five degrees in the interval of zero to 180 degrees.
a) the relationship between the torsion angle and number of cycles to failure can be conveniently interpolated as linear in the case of cycles around zero; a sort of saturation is met for large rotations in the case of cycles between positive peaks;
Firstly, a three-dimensional representation of the compound of interest is created in Cartesian space using the known atom types and connectivity in conjunction with tabulated bond lengths, bond angles and bond torsion angles where appropriate.
The torsion angle of 30[degrees] differs from that of the solid-state crystal structure, which is a coplanar structure (torsion angle 0[degrees]) (McKinney and Singh 1988).
A 3-D viewer window shows the continuous rotation about the x, y and z axes, and enables the calculation of bond angle and length, as well as torsion angle.
Denote the torsion angle about torsional center and warping displacement by [theta](z) and [beta] (z).
The torsion strain is measured by the attachment, which identifies torsion angle [phi] in the working part of the specimen.
i] ( measured in the rotation joints with transducers); [DELTA][alpha], [DELTA]a, [DELTA]d, [DELTA][beta] are the error vectors of the torsion angle [[alpha].
In use, bushings experience radial and axial loads and they rotate through a torsion angle as shown in figure 2.
