FEARCE - Durability analysis
FEARCE incorporates a fatigue module that includes a large array of linear and non-linear durability algorithms. Linear algorithms include the Goodman and Gerber methods. Multiaxial algorithms include the Dang Van, McDiarmid and Goodman methods. For non-linear analyses, the SWT, Brown-Miller, and Fatemi and Socie methods can be employed.
In addition to the variety of fatigue algorithms, FEARCE also provides alternative approaches to calculating a stress tensor from principal stresses. These include the Von Mises approach (signed and unsigned), the maximum principal stress approach, the P1 principal stress approach and the ASME approach.
FEARCE can perform reliability calculations defined by standard deviation on all material properties and loads. This enables the calculation of the number of failures within a given life span. FEARCE can also calculate fatigue safety factors for defined regions based on defined life, stress histories for non-linear analyses, and Haigh and Dang Van diagrams for linear analyses. All results can be displayed on the actual finite element (FE) model as numeric values or colour contours.
