力學(Mechanics)

力學是科學的一個領域,涉及物體在受力或位移時的行為,以及物體對其環境的後續影響。它是經典物理學的一個分支,處理處於靜止狀態或以明顯低於光速的速度運動的粒子。主要處理物體的運動和力。

透過頻繁的試驗,可以觀察到,當使用相同的軸向力拉伸兩個大小、外形完全相同的鋼棒和橡膠棒(這意味著,將產生相同的軸向應力)時,兩種棒體產生了不同的伸長量。在力學中,兩種棒體材料的差異可由應力和應變分量之間的關係來表示。透過將這種關係表示為行矩陣,即

我們將得到

其中,X 為一個可表徵棒體材料的 5×5 矩陣,通常被稱為彈性矩陣;它的分量被稱為棒體材料之彈力或彈性常量。在方程式 (2) 中,剪切應變已乘以 2;定義 (1) 和 (2) 確保。方程式 (3) 呈現的應力與應變之間的關係被稱為棒體材料的物性關係。在方程式 (3) 中,假定在測量應變 d 的參考組態中,棒體不受應力作用。

  1. [主詞動詞一致] [文法]
    experimentation是單數因此要用單數的has,主詞動詞單複數必須一致。
  2. [用字遣詞]
    使用適切的用詞讓文意更清晰、提升可讀性。
  3. [不當省略]
    “in the materials”被省略了。
  4. [用字遣詞]
    學術寫作裡資訊需精準、簡潔地呈現。正式的語言是學術英文的指標。表示精鍊語言的其中一種方法是將片語動詞改成正式用語。這裡writing改成expressing會比較好。
  5. [文意清晰與否]
    使用適切的用詞讓文意更清晰。
  6. [標點符號]
    美式英文應該在拉丁縮寫如i.e.以及e.g.之後用逗號。
  7. [風格]
    這種情況下應用萬國碼(×)而不是用字母x。這個符號前後都要插入空格。
  8. [標點符號]
    分號比逗號要來得強,比句號要來得弱。當兩個語句意義緊密結合卻沒有相應的連結詞則使用分號。
  9. [文法]
    修正文法問題。
  10. [術語選擇]
    選擇正確術語。
  11. [用字遣詞]
    選擇正確用詞。
  12. [可讀性]
    使用更精準簡潔的用詞提升可讀性。
  13. [風格]
    需使用連字號來保存某些可能漏失的語意。

Here, X is a 5 × 5 matrix that characterizes the material of the body. It is generally known as the elasticity matrix; its components are called elasticities or elastic constants for the material of the body. The shear strains have been multiplied by 2 in Eq. (2); definitions (1) and (2) ensure that . The stress–strain relation shown in Eq. (3) is known as the constitutive relation for the material of the body. It is assumed in Eq. (3) that the body is stress-free in the reference configuration from which the strain d is measured.
