Workshop and Tutorial topics are chosen based on the general interest suitable for the PVP Conference attendees. Admission to the workshops and the tutorial sessions is free and they are open to anyone who is a registered conference attendee. Tutorials are scheduled during regular conference session blocks.

Workshops

Acoustic Emission In Metals And Composites
Part I, Sunday, July 17, 9:00 am - 11:30 am, Harborside Ballroom, Salon B
Part II, Sunday, July 17, 1:00 pm - 3:30 pm, Harborside Ballroom, Salon B
Sponsored by the MISTRAS Group and the ASME NDE Division.

This is a two-session workshop intended to provide the attendee with a basic understanding of the Acoustic Emission (AE) phenomena, the terminology, and how it applies to testing metals and composites. Brief descriptions of each session follow.

Part I (Morning Session): Dr. Ronnie Miller will discuss the following topics related to AE in metals:

• Definition of AE as a nondestructive testing (NDT) technique
• Sources of AE energy
• Events in metals detectable by AE technology
• Differences between AE and other NDT methods
• Typical applications of AE technology in laboratory and field testing
• Review of applicable industry codes and standards and ASME code cases
• Desktop demonstration of AE in metals

Part II (Afternoon Session):, Dr. Adrian Pollock will discuss the following topics related to AE in composites:

• Use of AE in the evaluation of mechanical integrity of composite materials and structures
• Effectiveness of AE as a research and development tool
• Basic AE phenomena in composites
• Source mechanisms of AE in composites
• Relationships between different sources and the related AE signals
• Examples of industrial applications.
• Review of applicable industry codes and standards and ASME code cases
• Desktop demonstration of AE in composites

Tutorials

Special Tutorial is a 2 hour conference session usually held on Sunday afternoon. The session leader will make available any necessary presentation material.

Technical Tutorials are a ½ day conference sessions and are integrated in the conference schedule. Attendees may purchase a set of the "Tutorial Notes"; the charge is set as low as possible based on the cost of production.

• Each attendee will receive a "Certificate of Attendance" as a proof that the attendee has participated in the "2 hour Special Tutorial" or the "4 hour Technical Tutorial."
• VP Division will not assign Continuing Education Units (CEU) on these certificates however; attendees may negotiate CEU credits with their respective licensing boards.

Following is the line-up for the tutorial sessions for the 2011 PVP conference.

Special Tutorial
Process and Benefits of ASME Pressure Technology Codes and Standards Development
Sunday, July 17, 4:00 pm - 6:00 pm, Harborside Ballroom, Salon B
Guido Karcher - Chair of Board on Pressure Technology Codes and Standards
Lou Hayden - Past Chair of Board on Pressure Technology Codes and Standards
Bill Bees - ASME PVP Senator

Have you ever had a curious interest in how all of the Codes and Standards that ASME produces are developed? In addition to the advantages and benefits that ASME members gain from attendance and participation in the ASME Pressure Vessel and Piping Conference, ASME can also offer additional benefits to people interested in the development of Codes and Standards. This special tutorial will:

• Explain the overall process used in development of ASME Codes and Standards, and specifically those in the area of Pressure Technology Codes and Standards.
• Describe the consensus process used in Codes and Standards development and the ANSI approval process
• Explore the benefits to participants in ASME Codes and Standards development activities
• Discuss the various types of participation in the Codes and Standards Committees, qualifications, and the expectations of the participants
• Explore the relationship between ASME Pressure Vessel and Piping Division and ASME Codes and Standards
• Explain the overall committee structure under the Board on Pressure Technology Codes and Standards and their areas of responsibilities
• Discuss some of the "emerging" areas in Pressure Technology and the ones currently seeking participants.

One of ASME's most valuable assets is our relationships with the volunteer members who serve on our Codes and Standards committees. It is ASME's policy to afford all persons with direct and material interest, without regard to country of citizenship or residency, the opportunity to participate in the ASME Codes and Standards development process. Membership on a committee normally represents you as an individual, rather than as a representative of your employer or another organization.

The last part of the session will be an open question and answer period to discuss any questions you may have. Come and ask the experts about another way to get involved with ASME!

Technical Tutorial I
ASME Section VIII, Division 3 Alternative Rules for Construction of High Pressure Vessels
Monday, July 18, 2:00 pm - 5:45 pm, Harborside Ballroom, Salon B
J. Robert Sims, Becht Engineering Co., Inc.

This tutorial focuses on the differences between Section VIII, Division 3 (Alternative Rules for Construction of High Pressure Vessels) and Section VIII, Division 2 (Alternative Rules for Pressure Vessels). Requirements for materials, design, fabrication and testing will be presented, with special emphasis on the following areas:

• Methods for calculation of residual stresses due to autofrettage
  
  • Using closed form solutions
  • Using finite element analysis
• Methods for fracture mechanics analysis to determine the design fatigue life.
  
  • Detailed examples will be provided.
• Methods for correcting the traditional "S-N" fatigue life calculations for mean stress.
• Differences in elastic-plastic analysis and structural stress methods compared to Division 2.
• Fracture toughness testing requirements
• Fabrication requirements.

Technical Tutorial II
Uncertainty Assessment in Engineering Design and Analysis
Tuesday, July 19, 2:00 pm - 5:45 pm, Harborside Ballroom, Salon B
Narendra Gupta, Savannah River National Laboratory

This tutorial will present some basic concepts and tools to assess uncertainty that an analyst should be familiar with while using computational models for analysis. The following topics will be discussed:

• What is uncertainty?
• Uncertainty and sensitivity
• Probability distributions and basic statistics
• Basic concepts of Design of Experiments (DOE)
• Sampling schemes used in assessing uncertainty
• Propagation of uncertainty in computational models
• Uncertainty and decision analysis

Technical Tutorial III
Flow-Induced Vibration Of Heat Exchangers And Steam Generators
Wednesday, July 20, 8:30 am - 12:15 pm, Harborside Ballroom, Salon B
Michel Pettigrew, École Polytechnique

This tutorial is for the non-specialist and will cover the following basic steps to analyze a shell-and-tube heat exchanger:

• Flow velocity distribution
• Tube frequencies and mode shapes
• Tube damping in gases, liquids and two-phase flows
• Vibration excitation mechanisms (fluidelastic instability, vortex shedding resonance, random turbulence, and acoustic resonance)
• Vibration response calculations
• Fretting-wear damage prediction
• Design guidelines.

The participants are asked to bring their calculators and do sample calculations. A heat exchanger will be analyzed from a vibration point of view with the participation of the attendees.
