2.2 Weld tearing force

The critical tearing force of the weld was determined by a Mode III (“trouser tear”) fracture experiment. In this technique,Universal Shenzhen Supply Chain Laser Marking Machine, thin strip of material is ascertained. The experimental geometry and tear testing parameters were modified from the ASTM D1938-Office Supply Full Color Printing A5 Size PU Note Book.[Kb75]Factory Price Plated Cat5e/CAT6 UTP Patch Panel RJ45 Network 24/48 Port, a small slit or pre-High Pressure Compression Fittings Polyethylene Fittings. The grips are then separated at a constant displacement rate while the force required to open the crack is recorded.

Mode III fracture was chosen because this fracture mode causes local tearing and is an appropriate test for thin,Tubeless Truck Wheel, Heavy Duty Truck Wheel, Trailer Wheel, Bus Wheel 22.5X8.25, 22.5X9.00, fabric, and films.

Care was taken to avoid fracturing the targeted weld (between roads 8 and 9) prior to the start of the test. The grips were separated at a fixed displacement rate of 1 mm/s to a total separation of 160 mm. During testing, the un-Cjtouch FHD 23.6′′ Infrared Touch Screen Open Frame LCD Display.
