Material Strength Using Steady Bending Forces TRIZ Cases
- Metal Sheet Forming Limits With 3D Bending-Strain Mapping
Bulge tests with hemispherical punches of different curvatures add bending deformation to forming-limit analysis for more accurate fracture prediction.
- Flexible Material Rolling Evaluation With Flatness and Tension Control
Controlled rolling and sliding keep flexible material flat under even tension, enabling durable testing without wrinkling or substrate damage.
- Deformed Rebar Bending With Multi-Angle Springback Prediction
Multiple released-angle measurements capture elastic springback in deformed reinforcing bars, enabling more accurate target-angle bending.
- Sheared Edge Bend Crack Evaluation in Press-Formed Steel Parts
Bend outer side strain and die bend radius are used to predict sheared-edge cracking before press forming high-strength steel parts.
- Double-Sliding Folding Mechanism for Low-Stress Flexible Materials
Interlocking horizontal and inclined sliders correct folding motion to minimize stress on flexible materials during durability testing.
- Sheared Edge Crack Evaluation in Press-Formed Steel Bending
Calculating a crack index from bend strain and die radius helps predict sheared-edge bending cracks in press-formed steel parts.
