可测试项目 
（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

●抽出力         ●粘合力及取峰值计算值 
●压力试验       ●粘合力剥离力试验 
●弯曲试验       ●拔出力穿刺力试验 

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zui大应力即为比极限。 
3.弹性限：为材料所能承受而不呈*变形之zui大应力。 
4.弹性变形：除去荷重后，材料的变形*消失。 
5.*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，*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： 
在拉力机上，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。

Three point bending test project of the universal testing machine: 
1. The elastic coefficient of the elastic young's modulus 
Definition: and with the method of phase to the ratio of strain to stress components and the method. For the determination of rigid coefficient of the material, the higher its value, the material, the more strong. 
2. The ratio limit: load within a certain range is proportional to the elongation can maintain the relationship, the maximum stress is than the limit. 
3. The elastic limit: for materials are not showed the maximum stress of permanent deformation. 
4. Elastic deformation: after removing the load, material deformation disappear entirely. 
5. Permanent deformation: after removing the load, the material is still residual deformation. 
6. The yield point, tensile, deformation increase fast and stress constant, this point is the yield point. The yield point is divided into upper and lower yield point, yield point above as a general yield point. 
The yield (yield) : load exceed ratio is proportional to the elongation is no longer, dangerously load, and then for a period of time, ups and downs, elongation, great changes have taken place this kind of phenomenon is called the yield. 
7. The yield strength, tensile, permanent elongation reaches a certain specified value of the load, divided by the parallel of the original sectional area, the income of the business. 
8. Spring K value: with deformation phase reaction component and the ratio of the deformation. 
9. The effective elastic and hysteresis loss: 
In tensile machine, the sample at a certain speed stretch to a certain elongation or stretching to the regulation of load, contraction measured sample recovery work and for the consumption of the percentage of the ratio of the work, is the effective elastic; Lost when the specimen elongation, shrinkage is measured with the percentage of elongation is consumed when the ratio of the work, is the hysteresis loss.
