Workbench Mechanical defines creep limit ratio to 1 as a default value. It is a ratio of equivalent creep strain increment and the modified equivalent elastic strain Creep Limit Ratio is the maximum allowable limit to the creep Strain Ratio. If, during a timestep, the solver calculates a Creep Strain Ratio larger than the Creep Limit Ratio (default =1.0), then the solution is automatically bisected until the creep limit is satisfied or the minimum time step is reached. Although WB-Mechanical sets this limit to 1.0 by default, a creep limit ratio of 0.1 to 10 (10-1000%) is generally recommended, depending on the magnitude of the equivalent elastic strain developed and the level of accuracy required.<\/p>\n","protected":false},"template":"","class_list":["post-165458","topic","type-topic","status-publish","hentry","topic-tag-4391","topic-tag-materials","topic-tag-mechanical","topic-tag-special-purpose","topic-tag-structural-mechanics"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
