On the Load-Displacement Relation for a Cracked Rectangular Specimen with Constrained Ends

摘要

Relations are presented between the net force, the end displacement, and the stress intensity factor for cracked rectangualar panels subjected to uniform displacement. Two configurations are considered: an edge-cracked panel and a center-cracked panel. If the stress intensity factor is already known in terms of the normal displacement, then the resulting formulation allows the determination of that stress intensity in terms of the applied load and vice versa.
