中文摘要 | 混凝土為工程上用於抗壓材料,因此混凝土試體受壓過程的觀察,對試體抗壓程度的瞭解非常重要,但是當受壓過程中之應變值等於0.003~0.004時,試體即破壞,且其為微量變形,所以受壓過程不易觀察。因此,本文利用假設材料為等向性且遵守能量守恆定理,推導出其受壓後之側向變形與軸半徑變化函數。本文所推導出的結果,再配合數學軟體Maple,來模擬混凝土試體,在受壓過程中變形狀況,由此3-D動態可視法模擬受壓過程,發現所推演之方程式與電腦模擬變形狀況相符合。因此本文所建立的函數模式,對混凝土試體受壓過程提供了有效且深入的詮釋,本函數模式更可進一步推廣至其他可壓縮材料的測試上。 |
英文摘要 | Concrete is used for resisting compressive force, but a concrete cylinder will crack at a strain value around 0.003~0.004 when deformation is trifling. It is assumed that the material should be isotropic and should observe the principle of strain energy. The functions of side and radius deformation can be inferred and then the mathematical software Maple is used to simulate the concrete cylinder being compressed. It is found that the inferred functions, and the deformations of concrete cylinder simulated by the Maple software are matched. In this paper, effective and intelligible knowledge of the mathematical model of concrete cylinders being compressed is supplied. These results of 3-D dynamic visualizing are obtained from the simulation, so this method can be applied to other compressive material. |
