brittle fracture的音標是[?br?t?l frak?t??r?t]，基本翻譯是脆性斷裂。速記技巧：將單詞拆分記憶，brittle是易碎的，脆性的，fracture是斷裂，結合記憶。

Brittle fracture 的英文詞源是 brittleness，這個詞源自拉丁語 brittum，意為“脆的”。

brittle fracture 的變化形式主要有兩種。一種是 brittle crack，表示脆性裂紋，是 brittle fracture 的一個常見結果。另一種是 brittleness index，表示脆性指數，是用來衡量材料脆性斷裂可能性的指標。

相關單詞包括：

1. brittle crack - 脆性裂紋，是 brittle fracture 的一個常見結果，表示材料在受到應力時容易產生裂紋。

2. ductile fracture - 延性斷裂，與 brittle fracture 相反，表示材料在受到應力時能夠產生塑性變形。

3. elastic limit - 彈性極限，表示材料在受到應力時能夠保持彈性形變的最小應力值。

4. stress corrosion cracking - 應力腐蝕開裂，是一種環境因素與材料脆性斷裂相互作用的破壞形式。

5. fatigue cracking - 疲勞裂紋，表示材料在反復應力作用下容易產生裂紋。

6. impact testing - 沖擊測試，用于評估材料的脆性性質，通過測定其抗沖擊能力來評估其 brittleness index。

7. fracture toughness - 斷裂韌性，表示材料抵抗裂紋擴展的能力，是衡量 brittleness index 的重要指標之一。

8. fracture toughness testing - 斷裂韌性測試，用于測量材料的韌性值和 brittleness index。

9. fracture surface - 斷裂表面，表示材料斷裂時的表面形貌，可以用來評估材料的脆性性質。

10. fracture toughness limit - 斷裂韌性極限，表示材料在受到特定應力時能夠抵抗裂紋擴展的最大值。

Brittle fracture is a common fracture mode in engineering materials, which often occurs due to sudden impact or stress concentration.

常用短語：

1. brittle fracture occurs

2. prevent brittle fracture

3. impact resistance and brittle fracture

4. stress concentration and brittle fracture

5. brittle fracture risk

6. brittle fracture analysis

7. brittle fracture mechanism

雙語例句：

1. The impact of a sudden impact can cause brittle fracture.

2. The high-strength steel has better impact resistance and less tendency to brittle fracture.

3. The stress concentration at the joint may lead to brittle fracture.

4. The aging process can reduce the brittle fracture risk of the material.

5. The brittle fracture analysis is necessary for the design of the structure.

6. Understanding the brittle fracture mechanism is helpful for preventing it.

7. The brittle fracture of a bridge caused a traffic accident.

英文小作文：

Brittle fracture is a common problem in engineering materials, which can lead to sudden failure or unexpected accidents. Therefore, it is necessary to take measures to prevent brittle fracture, such as improving the impact resistance and reducing the stress concentration of materials, optimizing the design of structures, and understanding the brittle fracture mechanism. In addition, aging treatment and maintenance can also reduce the risk of brittle fracture. However, if brittle fracture occurs, it may cause significant economic losses and safety hazards, so it is necessary to take timely measures to minimize its impact on society and economy.
