Abstract
With the advent of new low-cost and powerful computers and explicit time-
integration FEM codes, three-dimensional models are now available for the
transient response analysis of buried structures due to blast explosions in their
proximity. In the industrial domain, a most interesting issue is to determine the
critical distance between the center of the explosion and the buried structure in
order to insure its integrity. In the present paper a systematic study is presented
on the stresses induced to buried pipelines, focussing on their curved parts such
as elbows and tees. In more detail, it was examined whether the curved parts of a
pipeline suffer more compared to the straight parts. For the purposes of the
present study, the d
