測試項目：

（一）普通測試項目：（普通顯示值及計算值）
●拉伸應力　　　●拉伸強度                 ●扯斷強度　　　●扯斷伸長率
●定伸應力　　　●定應力伸長率           ●定應力力值　　●撕裂強度
●任意點力值　　●任意點伸長率           ●抽出力　　　　●粘合力及取峰值計算值
●壓力試驗　　　●剪切剝離力試驗        ●彎曲試驗　　　●拔出力穿刺力試驗

（二）特殊測試項目：
1.彈性系數即彈性楊氏模量定義：同相位的法向應力分量與法向應變之比。為測定材料剛性之系數，其值越高，材料越強韌。
2.比例限：荷重在一定范圍內與伸長可以維持成正比之關系，其醉大應力即為比極限。
3.彈性限：為材料所能承受而不呈永久變形之醉大應力。
4.彈性變形：除去荷重后，材料的變形完全消失。
5.永久變形：除去荷重后，材料仍殘留變形。
6.屈服點：材料拉伸時，變形增快而應力不變，此點即為屈服點。屈服點分為上下屈服點，一般以上屈服點作為屈服點。屈服（yield）：荷重超過比例限與伸長不再成正比，荷重會突降，然后在一段時間內，上下起伏，伸長發生較大變化，這種現象叫作屈服。
7.屈服強度：拉伸時，永久伸長率達到某一規定值之荷重，除以平行部原斷面積，所得之商。
8.彈簧K值：與變形同相位的作用力分量與形變之比。
9.有效彈性和滯后損失：在復合材料拉力試驗機上，以一定的速度將試樣拉伸到一定的伸長率或拉伸到規定的負荷時，測定試樣收縮時恢復的功和伸張時消耗的功之比的百分數，即為有效彈性；測定試樣伸長、收縮時所損失的能與伸長時所消耗的功之比的百分數，即為滯后損失。

Test items:

（1） Common test items: (common display value and calculated value)

● Tensile stress ● Tensile strength ● Breaking strength ● Elongation at break

● Constant elongation stress ● Constant stress elongation ● Constant stress value ● Tear strength

● Force value at any point ● Elongation at any point ● Extraction force ● Bonding force and peak value calculation

● Pressure test ● Shear peeling force test ● Bending test ● Pullout force puncture force test

（2） Special test items:

1. Definition of elastic coefficient, i.e. Young's modulus: the ratio of normal stress component and normal strain in the same phase. To determine the coefficient of material rigidity, the higher the value, the stronger the material.

2. Proportional limit: the load can maintain a proportional relationship with the elongation within a certain range, and its high stress is the specific limit.

3. Elastic limit: It refers to the large stress that the material can bear without permanent deformation.

4. Elastic deformation: after removing the load, the deformation of the material disappears completely.

5. Permanent deformation: after removing the load, the material still remains deformed.

6. Yield point: when the material is stretched, the deformation increases while the stress remains unchanged, which is called the yield point. The yield point is divided into upper and lower yield points. Generally, the upper yield point is taken as the yield point. Yield: When the load exceeds the proportional limit, it is no longer in direct proportion to the elongation. The load will drop suddenly, and then fluctuate up and down for a period of time. The elongation changes greatly. This phenomenon is called yield.

7. Yield strength: the quotient of the load when the permanent elongation reaches a specified value during tension divided by the original sectional area of the parallel part.

8. Spring K value: the ratio of force component in phase with deformation to deformation.

9. Effective elasticity and hysteresis loss: when the specimen is stretched to a certain elongation or specified load at a certain speed on the composite tensile testing machine, measure the percentage of the work recovered during the contraction of the specimen and the work consumed during the extension, which is the effective elasticity; Determine the percentage of the ratio of the energy lost during the elongation and contraction of the sample to the work consumed during the elongation, which is the hysteresis loss.
