✦ Synopsis
The J-integral is evaluated for a SEN specimen under bending and tension, both in terms of loads and displacements and as the original path independent integral. A displacement J, determined for proportional loading, proved to give accurate results also under nonproportional loading. J also appeared to be independent of the load history. Finally, the three-dimensional failure assessment diagram that appears with two independent loads is discussed, and also how it can be reduced to two dimensions.

## Abstract For a ferritic construction steel similar to St37‐2 the cross section of three‐point bend type specimens was selected to be B : w = 1 : 2 and 1 : 1 (B: thickness, w: specimen width, and w = 25 mm was kept constant). For these two geometries the onset of stable crack growth J~0~ was foun
