Options are provided to request time history plots of various parameters relating to clashing analyses. These are as follows:
(i)The minimum clearance between element sets for which a clashing region is defined. A clearance value of zero indicates that contact has occurred. A value of less than zero indicates that some degree of relative penetration has occurred between the lines.
(ii)The total reaction force for a clashing region. If there is more than one clashing location the various reaction magnitudes are simply summed together. The reaction at any particular location is based on the contact stiffness times the relative penetration of the lines, plus any damping contribution (proportional to the relative velocity of approaching lines).
(iii)The clashing impulse. This is the integral of the reaction force with respect to time.
•*TIMETRACE is used to request the creation of timetrace plots. Specifically, the TYPE=CLASH inputs are used to request plots of the time history of clearance, reaction or impulse for clashing analyses.
