Title: Intro to ASME Section VIII, Division 2, Part 5 – Design By Analysis
Description: Design By Analysis to ASME Section VIII, Division 2, Part 5 is becoming more and more a part of everyday engineers’ work. But do you really know what to do and how to properly perform such analyses? In this full day special technical tutorial, we examine the technical approaches contained in Part 5. We start with the philosophical approach that Part 5 has introduced into Design By Analysis, and then we walk through the various failure modes: Plastic Collapse, Local Failure, Buckling, Ratcheting, Fatigue, and Creep. Tutorial attendees will be introduced to each of the failure modes, as well as the analytical methods to demonstrate that an adequate margin is demonstrated to protect against the failure modes.
Duration: This is a full-day tutorial, on Sunday before the conference in 4 blocks:
- TW-01: 8:00am-9:45am
- TW-02: 10:00am-11:45am
- TW-03: 12:45pm-2:30pm, and
- TW-04: 2:45pm-4:00pm

Title: Structural Dynamics for Extreme Loading Events of Vessels and Piping
Presenters: Robert Valdiviez, Jihui Geng, Megan Tribble, John Ludwigsen, Joshem Gibson and Matt Edel
Description: This tutorial is intended to provide engineers involved with the design, maintenance, certification, and/or management of capital assets with an understanding of the structural dynamic aspects that come to bear during extreme loading events. Extreme loading events, either intentional or unintentional, can be explosive detonation, large deflagration with or without a transition to detonation, boiling liquid expanding vapor explosion (BLEVE), high-speed impact from foreign projectiles, and high-speed impact of system components into each other, for example. Almost any type of loading event that imposes unusually high strain rates on the component’s materials of construction is of interest.

Title: Fracture Mechanics Applications for Piping
Presenters: Dr. Frederick (Bud) Brust, Dr. Gery Wilkowski, Engineering Mechanics Corporation of Columbus &
Dr. Suresh Kalyanam, Battelle Memorial Institute
Part 1: TW-07 Tuesday, July 21, 2:00-3:45pm
Part 2: TW-08 Tuesday, July 21, 4:15-6:00pm
Description: Fracture mechanics has been applied to plant piping and pipelines for flaw evaluation (assessment of an actual flaw found in service) and flaw tolerance evaluations (will leak before- break behavior occur). This technology has evolved considerably over the decades from the early assumptions of brittle fracture using linear elastic fracture mechanics. This tutorial will show the developments over time and various current technical aspects for modern flaw evaluation/flaw tolerance analyses. The tutorial is targeted for those new to flaw assessment/ tolerance analyses and provides some overview of methodologies for those willing to undertake advanced applications.
This tutorial includes five modules:
- Module 1: Background on fundamental aspects of fracture mechanics, and historical developments
- Module 2: Subcritical crack growth analyses and considerations
- Module 3: Material toughness/strength conditions
- Module 4: Failure modes and criteria for flawed pipes under quasi-static loading assumptions
- Module 5: Failure modes and criteria for flawed pipes under dynamic loading This important tutorial is planned to span of three sessions
