Tensile test/tensile strength test calculation formula summary

Abstract: 本文汇总了拉力试验和拉力强度测试的计算公式。对于哑铃状试验片，截面积计算为厚度乘以平行部分宽度。拉力强度通过断裂荷重除以试片截面积计算；伸长率通过断裂时和原标点距离的差异计算。粘着强度由剥离荷重除以试片宽度得出；撕裂强度通过最大荷重除以试片厚度计算。拉应力则在特定伸长率下通过荷重除以试片截面积得出。

1. Cross-sectional area of dumbbell-shaped test piece = thickness (cm) × width of parallel part (cm)


2. Tensile strength TB (Kg/cm2) = breaking load (kg) F B/section area of test piece ( c㎡ ) A


3. Elongation EB( %) = ( distance of punctuation point at break L1-distance of original punctuation point L0 )/ distance of original punctuation point L0 x 100%


4. Adhesive strength TF (Kg/c㎡) = peeling load (kg) F F/test piece width (cm) b


5. Tear strength TS (Kg/cm2) = maximum load (kg) FS/test piece thickness (cm) t


6. Tensile stress M M (Kg/cm 2 ) = load at specific elongation (kg) Fn/cross-sectional area of test piece (cm 2 ) A


(The n of Mn here means the specific elongation (%), for example, M300 means the tensile stress when the elongation is 300%).
