可測試項目 
（一）普通測試項目：（普通顯示值及計算值）

●彎曲試驗       ●拔出力穿刺力試驗 

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zui大應力即為比極限。 
3.彈性限：為材料所能承受而不呈*變形之zui大應力。 
4.彈性變形：除去荷重后，材料的變形*消失。 
5.*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(fā)生較大變化，這種現象叫作屈服。
7.屈服強度：拉伸時，*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： 
在拉力機上，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。

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.
