（一）普通測試項目：（普通顯示值及計算值）

（二）特殊測試項目：
1.彈性系數(shù)即彈性楊氏模量定義：同相位的法向應(yīng)力分量與法向應(yīng)變之比。為測定材料剛性之系數(shù)，其值越高，材料越強韌。
2.比例限：荷重在一定范圍內(nèi)與伸長可以維持成正比之關(guān)系，其最大應(yīng)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最大應(yīng)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(yīng)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(nèi)，上下起伏，伸長發(fā)生較大變化，這種現(xiàn)象叫作屈服。
7.屈服強度：拉伸時，永久伸長率達到某一規(guī)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(fù)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(guī)定的負荷時，測定試樣收縮時恢復(fù)的功和伸張時消耗的功之比的百分數(shù)，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(shù)，即為滯后損失。

Tensile test

One is to select the measuring range based on the sample, hang the thallium and align it with the engraved line, and adjust the buffer valve to match the measuring range. The second is to turn on the power, start the oil pump, and open the oil delivery valve to make the piston rise and fall 200mm, 2-3 times. The third step is to raise the piston by 20mm to 40mm and align the pointer with the zero position. Fourthly, adjust the moving crossbeam to the appropriate position. Close the oil delivery valve, press the "open" and "clamp" buttons on the clamp, clamp the sample, and be sure to keep the sample in a vertical position and in the middle. Adjust the indicator disk speed according to the loading speed required by the experiment. The fifth step is to open the oil delivery valve and start loading, so that the rotation speed of the pointer is basically consistent with the speed of the tracking disc. After the sample is damaged, close the oil delivery valve, record the test data, return the passive needle to zero position, and remove the fractured sample. Seven is to repeat the content from two to six and continue with the next experiment.

（1）Common testing items: (common display values and calculated values)

● Tensile stress ● Tensile strength ● Tensile strength ● Tensile elongation at break

● Constant tensile stress ● Constant elongation at constant stress ● Constant stress value ● Tear strength

● Force value at any point ● Elongation rate at any point ● Pull out force ● Adhesive force and peak value calculation

● Pressure test ● Shear peeling force test ● Bending test ● Pull out force puncture force test

（2）Special testing items:

1. Elastic modulus, also known as Young's modulus of elasticity, is defined as the ratio of the normal stress component to the normal strain in the same phase. To determine the coefficient of material rigidity, the higher the value, the stronger the material.

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

3. Elastic limit: The maximum stress that a material can withstand without permanent deformation.

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

5. Permanent deformation: After removing the load, the material still retains deformation.

6. Yield point: When a material is stretched, the deformation increases while the stress remains constant, and this point is called the yield point. The yield point is divided into upper and lower yield points, and generally the upper yield point is taken as the yield point. Yield: When the load exceeds the proportional limit and elongation is no longer proportional, the load will suddenly drop, and then fluctuate up and down over a period of time, causing significant changes in elongation. This phenomenon is called yield.

7. Yield strength: The quotient obtained by dividing the load at which the permanent elongation reaches a specified value during stretching by the original cross-sectional area of the parallel part.

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

9. Effective elasticity and hysteresis loss: On a composite material tensile testing machine, when the specimen is stretched at a certain speed to a certain elongation or to a specified load, the percentage of the work recovered during shrinkage and the work consumed during stretching is measured, which is the effective elasticity; The percentage of the energy lost during the elongation and contraction of a sample compared to the work consumed during elongation is called hysteresis loss.
