  • 非線性粘彈性

Examples

  • High molecule physics and the damage theory of rheologic material with lacuna are used in experiments to study the pmma ' s nonlinear viscoelasticity and changing depends on time and temperature when distorting and destroying . we try to seek a common rule to polymer ' s crazing damage , offer a viable damage model and measure to research polymer ' s minute damage
    本文運用高分子物理、含缺陷流變性物體的材料破壞等理論，以實驗為基礎，對聚合物變形、破壞以及時間相依和溫度依賴性等非線性力學行為進行研究，試圖尋求聚合物銀紋損傷的一般規(guī)律，為研究聚合物的細觀損傷提供了一種可行的損傷模型與方法。
  • ( 2 ) using craze density dcraze ( , ) to illustrate the damage degree of material , considering strain equivalent hypothesis , non - linear visco - elastic constitutive equation of pmma taken into consideration of the operation of craze damage is arrived . the pmma sheet is loaded under different forces to validate the non - linear visco - elastic constitutive equation with damage . the result shows that the theory curves obtained by the nonlinear viscoelasticity constitutive relation agrees with experimental data considerably well
    ( 2 )用銀紋密度d _ ( craze ) ( ， t )來描述材料的損傷度d ，在考慮應變等效性假設的基礎上，得到了pmma材料考慮損傷的非線性粘彈性材料的本構關系，運用此方程對材料在不同載荷水平下進行蠕變實驗，從而對蠕變條件下的應變響應進行模擬和預報。
  • In this paper , we take high molecule physics and the damage theory of rheologic material with lacuna as the basic , make the experiment as a mostly measure , take the pmma as a research object , to study the pmma ' s nonlinear viscoelasticity of high polymer . the technique showing minute details in minute view measure is used by the author to observe the change of crazing damage density follow the change of stress , time and temperature in term of creep and flab
    本文以高分子物理學、含缺陷流變性物體的材料破壞理論為基礎，以實驗為手段，以工程中常用的pmma為研究對象，對pmma銀紋破壞的非線性力學行為進行了研究。作者采用顯微技術，對pmma在蠕變或松弛條件下，不同應力水平和不同基溫下的pmma銀紋損傷進行了實驗研究。
  • The main purpose of this paper is to study crack growth rate of a class of nonlinear viscoelastic materials under the condition of constant load and small - strain . in this paper : the new test program is raised by referencing the existing test programs and by our trial and error ; in the new test program , facilities involved in the nonlinear viscoelastic crack tests are relatively few , the test process is relatively simple and the data obtained from the experiments are credible . on this basic , the calculation of j integral of nonlinear viscoelastic double cantilever beams specimens and the parameter of fracture work of corresponding nonlinear viscoelasticity are derived
