Multiple crack propagation by DBEM in a riveted butt-joint: a simplified bidimensional approach

Show other versions (1)

A Multi-Site Damage (MSD) crack growth simulation is presented, carried out by means of Dual Boundary Element Method (DBEM), in a two-dimensional analysis of a cracked butt-joint made of aluminium 2024 T3. An equivalent crack length is proposed for an approximated 2D analysis of a 3D problem where...
