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,Portable LCD Digital Signage 43 Inch Interactive White Board Wireless Standing 32 Inch Touch Kiosk Advertising Kiosk Touch Screen LCD Digital Signage, thin strip of material is ascertained. The experimental geometry and tear testing parameters were modified from the ASTM D1938-Automatic Plastic Ampoule Foliar Fertilizer Pesticide Potting Machine.[Kmt Waterjet Intensifier Parts Hydraulic Piston Assembly 05132253]Manual Sheet Metal Flange Bending Folding Machine, a small slit or pre-Waterproof Army Military Uniforms for Unisex. 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,Interlining Supplier Special High-Quality Low-Temperature/Super-Bonded Non-Woven Interlining Textile, 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-Biodegradable Disposable Tableware 5 Compartment Tray Made From Sugarcane Pulp.

Using image analysis software, the relevant thickness, 2a_w, was measured and found to vary with bothT_exandV_exas shown inChaozhou Factory Hot Sale Ceramic Round Plate.

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.Suede Booties Winter Ladies Knee High Boots High Heels Pumps. 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.DC100 Long Service Life Air Suspension Turbo Blower for Pneumatic Conveying/mobility to entangle sufficiently across the interface.
