A computational model for residual life assessment of dents generated by explosive loads in pipelines
(2003)The present work develops a finite elements computational model that describes the process of dynamic deformation in pipelines under explosive loads. The mechanical response of the material is modeled by means of an ... -
Use of deep learning algorithms for real-time detection of vessels in confined spaces using the Tensorflow framework
