# Material Testing Planning Skill ## Purpose The Material Testing Planning skill provides capabilities for planning and specifying mechanical material tests per ASTM standards, enabling proper test specimen design, test matrix development, and data analysis for property determination. ## Capabilities - Tensile testing specification (ASTM E8) - Hardness testing methods (Rockwell, Brinell, Vickers) - Impact testing (Charpy, Izod) per ASTM E23 - Fatigue testing (ASTM E466, E606) - Test specimen design and preparation - Test matrix development and optimization - Data analysis and property determination - Test report generation ## Usage Guidelines ### Tensile Testing (ASTM E8/E8M) #### Specimen Design 1. **Standard Specimens** | Type | Gauge Length | Gauge Width | Application | |------|--------------|-------------|-------------| | Sheet (flat) | 50 mm | 12.5 mm | Sheet/plate < 6 mm | | Round | 50 mm | 12.5 mm dia | Bar/rod stock | | Subsize | 25 mm | 6 mm | Limited material | 2. **Specimen Preparation** - Machine finish on gauge section - Radius transitions per standard - Measure dimensions before test - Mark gauge length #### Test Parameters ``` Strain rate: 0.015 mm/mm/min (yield) 0.05-0.5 mm/mm/min (ultimate) Temperature: Ambient (23 +/- 5 C) or specified Extensometer: Class B-1 or better ``` #### Properties Determined - Yield strength (0.2% offset method) - Ultimate tensile strength - Elongation at fracture - Reduction of are...
