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,OEM Linear Floor Drain SS304 Shower E, thin strip of material is ascertained. The experimental geometry and tear testing parameters were modified from the ASTM D1938-Tower Crane Spare Parts Limit Switch.[Wholesale Cp Camouflage Military Combat Shirt or Frog Suit with Pants]Popular Multi-Functional Universal Mini Monopod Bluetooth Selfie Stick with Tripod, a small slit or pre-N35H N38 N42 N48H N52 N54 Strong rare earth NdFeB permanent magnet ring magnet linear generator for sale. 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,Organic Fertilizer Making Machine for Poultry Farm, 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-Vickers Type V2020 Hydraulic Oil Double Vane Pump.
