The present paper suggests a method to consider uncertainties in engineering structures in a computational scheme. Latin hypercube sampling is used to prepare input data of probabilistic parameters for subsequent deterministic simulations where the mechanical response is evaluated. The approach is a

β¦ Synopsis
The history of the development of practice in many engineering disciplines is, in large part, the story of failures, both imminent and actual, and of the changes to designs, standards and procedures made as the result of timely interventions or forensic analyses. All engineers, and more particularly structural engineers, should be failure literate. Failure literacy means knowing about the critical historical failure cases that have shaped the profession: not merely the surface technical details, but the environment, the communications difficulties and the procedural issues. In the US, an intensive effort has been under way for nearly a decade to promote failure literacy in engineering education and practice. A number of educational resources have been developed to make it easier for engineering students and practicing engineers to learn from failures.

A brief review is given of what may be meant by a "catastrophic engineering failure", particularly as it relates to situations involving fracture. Whether "fast fracture" is necessarily the same as "unstable" fracture--and whether it makes any difference anyway--is discussed. Since recoverable elas
