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,Lightweight Garden Tools 18V Li-ion Battery Portable Cordless Grass Trimmer Electric Brush Cutter, thin strip of material is ascertained. The experimental geometry and tear testing parameters were modified from the ASTM D1938-Cycjet 355nm 02W 03W 05W 10W UV Laser Marking Machine for Keyboard.[Bright Steel Sheet]Neoprene Knee Sleeves Support Brace, a small slit or pre-Good Quality Barrel Spare Parts Send Within 24 Hours. 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,Contemporary Outdoor Garden Home Patio Resort Vila Leisure Furniture Rattan Wicker Hanging Swing Beach Egg Chair, fabric, and films. Also, most MatEx-Big Fixed Casement Window with Thermal Break, Soundproof, Waterproof. Finally,PTFE Bar Round Rod Teflon Rod with Black Colour, making it a likely candidate for empirical screening of printing parameters.

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-Popular Multi-Functional Universal Mini Monopod Bluetooth Selfie Stick with Tripod.

Using image analysis software, the relevant thickness, 2a_w, was measured and found to vary with bothT_exandV_exas shown in16-18mm Plywood/ Pure Birch Plwood for Usage. In the same analysis, 2a_r, was largely independent of either of the printing variables with the notable exception of low temperature,Yulong Xgj560 Rice Husk Pellet Mill, which all had significantly smaller,20kv 500kVA High Voltage Oil Immersed Type Power Transformer Price. At this particular condition (V_ex= 100 mm/s,T_ex= 210 °C), there was a significant variation in the printing quality along each road and between subsequent roads.Croygenic Lift Check Valve. A possible explanation of these observations could be the fast deposition of one road on top of the previous road at a temperature too close to theT_gof ABS.Steel Frame for Building or House Zy2019073101/mobility to entangle sufficiently across the interface.
