Modified Mohr Failure Criterion
The Tensile Ultimate Stress and Compressive Ultimate Stress are the required material limits for Modified Mohr failure criterion When you select Modified Mohr as the Failure Criteria, you must specify values of Tensile Ultimate Stress and Compressive Ultimate Stress.
For more information about how the Modified Mohr failure criterion is calculated, see Shigley, Joseph Edward, Mechanical Engineering Design, First Metric Edition. New York: McGraw-Hill Book Company, 1986.
Each field that has a dimension can have its own units. Creo Simulate scales the values you enter when the units change.
Generally the modified Mohr failure criterion is used in the definition of brittle materials.
