In this video demo, we show how to easily define a subsurface residual stress (SRS) profile, due to shot peening or another surface treatment, and apply it to a large 3D part for computation of distortion.

In one of my conference presentations, I discussed variational crimes, noting that using point forces and point constraints in finite element analysis serves as examples of such crimes. In the question-and-answer session, I was asked: “If using point constraints is a variational crime, then how is it possible that the structure designed to refloat the Costa Concordia was full of those crimes and yet it worked just fine.” This question presented an opportunity for me to explain that finite element modeling (FEM) and finite element analysis (FEA) are complementary methods when analysts correctly understand their respective domains of application and use them accordingly. However, problems arise when FEM is used outside its scope, which is an all too frequent error.
Hill Engineering and ESRD have executed a joint marketing agreement to collaboratively promote the combined use of our software tools Broad Application for Modeling Failure (BAMF) and StressCheck Professional, respectively, for the engineering applications of fatigue and damage tolerance analysis.
