Scatter in Charpy Data Considered as a Transferrable Parameter

Charpy V-notch (CVN) impact
tests are the most widely used method for characterizing material toughness in
steel applications. While the CVN method is both cost-effective and efficient,
CVN data is limited when it comes to performing fitness-for-service or
remaining-life calculations. Correlated data between Charpy and other fracture
tests are used together for these purposes, but this is also a limited
solution, especially in modern steel applications.

EWI has developed as assessment
method that can characterize the ductile-to-brittle temperature transition
behavior for structural steels more reliably than other existing methods. The
approach can be applied to a wide range of modern steels including structural
pipeline and marine materials.

Bill Mohr, Principal
Engineer for Structural Integrity, has written a new paper, Scatter in Charpy Data Considered as a
Transferrable Parameter
, to discuss this new scatter assessment method and its
future applications.

Navigating the Engineering Demands of Electric Vehicles

Vehicle electrification – once considered a trend related primarily to the manufacturing and assembly of batteries – now affects nearly every aspect of today’s vehicles. As the demand for vehicle electrification rapidly increases, manufacturers and suppliers face an array of engineering challenges.

To help manufacturers prepare for and navigate the engineering demands that electric vehicle (EVs) and hybrid electric vehicles (HEVs) bring to the industry, EWI has developed a vehicle electrification overview and three technical papers that analyze major challenge areas and work that is being done to address them.

  • Addressing Critical Challenges in Vehicle Electrification: An EWI Overview
  • Multiple Challenges in Vehicle Electrification: Batteries and Beyond
  • Material Joining Challenges in the Cable and Wiring Systems of EV-HEVs
  • Joining Challenges in the Manufacture of Motors for Electric Vehicles – Stator Winding Assemblies

Vehicle Electrification Market

In 2016, EVs and HEVs accounted for 1% of all vehicle sales worldwide. By 2025, one study estimates that EVs and HEVs will account for 30% of sales worldwide. According to another study, 57% of all passenger vehicle sales will be electric by 2040.

What do you see as the most concerning issues today for vehicle electrification? What specific problems do you face at your company, and what information or services do you need to solve them?

EWI and PMA to present Advanced Sheet Metal Forming Technology Workshop on October 8-9

The EWI Forming Center will present an Advanced Sheet Metal Forming Technology workshop on October 9, 2019, in Columbus, OH. This year, EWI is pleased to co-sponsor this event with the Precision Metalforming Association (PMA). Members of the EWI Forming Center Consortium and PMA will receive a discounted rate for registration to the workshop.

The event will bring together OEMs, stampers, material producers,
forming equipment manufacturers, simulation software developers, lubricant
suppliers, and researchers to discuss important issues related to the current
practice and advancement of sheet metal forming technology.

Technical presentations and discussions will include:

  • Recent advances in cold, warm, and hot stamping technologies
  • Industry 4.0 applications for sheet metal forming (such as machine learning and in-line monitoring)
  • Industrial applications for GEN3 Steel and its technical merits/issues
  • Edge cracking – evaluation, prediction, and elimination
  • Successful applications of the servo-motor press in aluminum and AHSS forming
  • Forming simulations to consider the variation of the material properties and process conditions

The workshop will kick off on Tuesday, October 8
at 4:00 p.m. with an EWI facility tour followed by a 5:00 p.m. welcome
reception at EWI Headquarters in Columbus. Technical presentations and
discussions will run from 8:30 a.m. through 4:00 p.m. on Wednesday,
October 9
 at the nearby Fawcett Center on the campus of The Ohio
State University. To register, please click here.

The workshop program includes a Supplier Exhibition which will be open during all breaks and lunch.  Exhibitors are entitled to exhibit space with a table plus one participant spot in the workshop sessions. To take advantage of this opportunity, click here.

Opportunities to sponsor a breakfast, coffee break, or lunch during the workshop are available to all workshop participants. If you are interested, please contact Heidi Wilson at [email protected] for details.

We look forward to seeing you in October. If you have any questions about the technical program, contact Hyunok Kim ([email protected] or 614-688-5239). For event questions, contact Heidi Wilson at [email protected].
