Shear Pin Stress Concentration V-Notch vs. U shape grooved in bending

AI Thread Summary
The discussion focuses on the need for resources that compare stress concentrations in shear pins with V-notch grooves versus rounded grooves under bending conditions. The user is seeking specific charts or images that illustrate these differences, as existing references primarily address torsion rather than bending. They mention having found limited resources, including a reference to Roark's book and Petersen's Stress Concentration Factors, but these do not fully meet their needs. The request emphasizes the importance of visual aids in understanding the stress risers for different groove shapes. Overall, the conversation highlights a gap in available literature regarding shear pin stress concentrations in bending scenarios.

Can someone link a website or attach a picture of a chart distinguishing the differences between the stress risers in a shear pin (round circular shaft) with a V-notch groove versus if it was a rounded groove. I have been looking but can only find charts, tables and graphs for round circular bars with rounded grooves in beninding.

Thanks so much for any help you can provide!

I had already seen this reference but unfortunately it only provides regerence to V-notch in torsion, but not bending.
 
The only other reference is Petersen's Stress Concentration Factors, Ref. 6.1 from the attachment.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
