  Traction-separation relationship is an important material characteristic
describing the fracture behaviour of quasi-brittle solids. A new numerical
scheme for identification of the traction-separation relation by inverse
analysis of data obtained from various types of fracture tests is proposed. Due
to employing the concept of sequentially linear analysis, the method exhibits a
superior numerical stability and versatility. The applicability and
effectiveness of the proposed method is demonstrated on examples involving
identification of the traction-separation relationship using experimental data
from various test configurations.
