| Property | Description | Default(s) | Restrictions |
|---|---|---|---|
| Input | This property defines the input data. | Accepts input of following types:
|
|
| Minimal radius | The minimum radius of the integration region. About half the size of the smallest element at the top of the crack. | 0.01 | |
| Flat radius | The radius of constancy of the weight function. At least twice the size of the smallest element at the crack tip. | 0.06 | |
| Maximal radius | The maximum radius of the integration region. As a rule, no more than half the crack length. | 0.1 | |
| Contours | The number of integration subdomains for determining the J-integral. | 5 | |
| Young's modulus | 207 | ||
| Poisson ratio | 0.3 | ||
| Alpha | Thermal expansion coefficient. | 0 | |
| Crack radius | Crack radius (in the case of a circular or elliptical crack). | 0 | |
| Crack radius 2 | The second radius of the crack (in the case of an elliptical crack, along the axis 'Tangent vector 1'). | 0 | |
| Crack front center | The coordinates of the center of the front of the crack. | 0 0 0 | |
| Normal vector | Vector normal to crack plane. | 0 1 0 | |
| Tangent vector 1 | A vector tangent to the crack front at its beginning. | 0 0 1 | |
| Tangent vector 2 | A vector tangent to the crack front at its end. | 0 0 1 | |
| Symmetrical model | The input dataset describes part of a symmetric model. | 1 | Accepts boolean values (0 or 1). |
| Plane strain | If enabled, a plane strain state is used, otherwise a plane stress is used. | 0 | Accepts boolean values (0 or 1). |
| Temperature forces | The presence of temperature load. | 0 | Accepts boolean values (0 or 1). |
| Bulk forces | The presence of bulk forces. | 0 | Accepts boolean values (0 or 1). |
| Surface load at crack | The presence of load on the banks of the crack. | 0 | Accepts boolean values (0 or 1). |
