拉伸流变仪的根是是在20世纪初被发现的。Trouton在测试沥青和鞋匠所用蜡时，在这些材料上进行“扭转”和“牵引”变形。通过巧妙的实验他发现，单轴拉伸黏度是剪切黏度的三倍。
The roots of extensional rheometry are to be found at the very beginning of the 20th century. It was Trouton, who when experimenting with pitch and shoemaker’s wax, subjected these materials to “torsion” and “traction” deformations. He discovered through his ingenious experiments, that the uniaxial extension viscosity is three times the shear viscosity.”.…A variety of pitch which gave by traction method λ=4.3 x 1010 poise was found by torsion method to have a viscosity μ=1.4 x 1010 poise… F.T. Trouton (1906)”
