Warehouse Breakage
Warehouse Breakage Case Study Released

Read our just released case study on the Failure of Filled Bottles during Warehouse Storage…After being filled with a carbonated liquid, a number of 12 fluid ounce capacity non-refillable beverage containers were found broken in the warehouse within two days of filling. Open our Q2 e-Newsletter for the full case study HERE

Fried Egg Glass Contaminant
Award winning SEM Picture

Congratulations go out to Dr. Brandon Aldinger and Brad Salitrik for this award winning image taken on our JEOL IT-300LV Scanning Electron Microscope.  The image “Sunny-Side Up Egg” was selected as the winner for the month of January 2024 in the JEOL USA Image Contest.  With some color added for interest, this photomicrograph of an embedded material particle closely resembles a classic breakfast delight. The particle was inadvertently deposited inside a glass food jar during formation while the glass was still red-hot. The yellow 'yolk' in the image corresponds to an area enriched in tin, while the 'whites' correspond to areas that were bubbled and cracked due to reactions with the surrounding glass. Embedded particles on the interior of a glass container lower its strength; therefore, determining the composition of particles is the first step in eliminating the source of the contaminants.

Broken Coffee Carafe Case Study
Broken Coffee Carafe

What caused the carafe to fracture?

Were the applied tensile stresses too high or was the glass surface strength too low?

New Case Study Released
New Case Study Released

How do you know whether the cause of breakage in this non-refillable 12-ounce bottle was due to the tensile stresses being too high or whether the glass strengths were too low?

Interpreting AGR Design Reports
Interpreting AGR Design Reports

Join our new, free livestream event “Maximizing FEA Results: Interpreting an AGR Design Report”. This one-hour session, to be conducted on Thursday November 16 at 9 AM EST by Brad Salitrik, will walk you through the assumptions and background from which an AGR Design Report is produced. It will provide a detailed explanation of the key aspects of design, including:

Thickness Considerations
Glass strength calculations
Creation of the 3D model
FEA interpretation of Stress values
Pass levels establishment for expected loads
