测试项目：

（一）普通测试项目：（普通显示值及计算值）
●拉伸应力　　　●拉伸强度                 ●扯断强度　　　●扯断伸长率
●定伸应力　　　●定应力伸长率           ●定应力力值　　●撕裂强度
●任意点力值　　●任意点伸长率           ●抽出力　　　　●粘合力及取峰值计算值
●压力试验　　　●剪切剥离力试验        ●弯曲试验　　　●拔出力穿刺力试验

（二）特殊测试项目：
1.弹性系数即弹性杨氏模量定义：同相位的法向应力分量与法向应变之比。为测定材料刚性之系数，其值越高，材料越强韧。
2.比例限：荷重在一定范围内与伸长可以维持成正比之关系，其醉大应力即为比极限。
3.弹性限：为材料所能承受而不呈永久变形之醉大应力。
4.弹性变形：除去荷重后，材料的变形完全消失。
5.永久变形：除去荷重后，材料仍残留变形。
6.屈服点：材料拉伸时，变形增快而应力不变，此点即为屈服点。屈服点分为上下屈服点，一般以上屈服点作为屈服点。屈服（yield）：荷重超过比例限与伸长不再成正比，荷重会突降，然后在一段时间内，上下起伏，伸长发生较大变化，这种现象叫作屈服。
7.屈服强度：拉伸时，永久伸长率达到某一规定值之荷重，除以平行部原断面积，所得之商。
8.弹簧K值：与变形同相位的作用力分量与形变之比。
9.有效弹性和滞后损失：在复合材料拉力试验机上，以一定的速度将试样拉伸到一定的伸长率或拉伸到规定的负荷时，测定试样收缩时恢复的功和伸张时消耗的功之比的百分数，即为有效弹性；测定试样伸长、收缩时所损失的能与伸长时所消耗的功之比的百分数，即为滞后损失。

功能特点：采用国外先进技术，全数字放大、采集，显示稳定、精度高、使用方便。采用铝合金外罩，主机采用直流或交流伺服电机、精密减速机、高精度丝杠、具有传动平稳、噪音低、速度精度高、调速范围宽，使用寿命长等特点；液晶实时显示，可显示试验力、峰值、位移、速度、试验状态等，外观大方，使用方便，操作简单；具有限位、过载自动保护、试样断裂自动停机等功能。配置标准拉伸附具一套。

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.

The aluminum alloy housing is adopted, and the host machine adopts DC or AC servo motor, precision reducer, high-precision lead screw, featuring stable transmission, low noise, high speed accuracy, wide speed regulation range, long service life, etc; LCD real-time display, which can display test force, peak value, displacement, speed, test status, etc., with generous appearance, convenient use and simple operation; It has the functions of limit, automatic overload protection, automatic stop of sample fracture, etc. Equipped with a set of standard stretching accessories.
