brittle fracture

brittle fracture的音标是[ˈbrɪtɪl frakˈtʃərɪt]，基本翻译是脆性断裂。速记技巧：将单词拆分记忆，brittle是易碎的，脆性的，fracture是断裂，结合记忆。

Brittle fracture 的英文词源是 brittleness，这个词源自拉丁语 brittum，意为“脆的”。

brittle fracture 的变化形式主要有两种。一种是 brittle crack，表示脆性裂纹，是 brittle fracture 的一个常见结果。另一种是 brittleness index，表示脆性指数，是用来衡量材料脆性断裂可能性的指标。

相关单词包括：

1. brittle crack - 脆性裂纹，是 brittle fracture 的一个常见结果，表示材料在受到应力时容易产生裂纹。

2. ductile fracture - 延性断裂，与 brittle fracture 相反，表示材料在受到应力时能够产生塑性变形。

3. elastic limit - 弹性极限，表示材料在受到应力时能够保持弹性形变的最小应力值。

4. stress corrosion cracking - 应力腐蚀开裂，是一种环境因素与材料脆性断裂相互作用的破坏形式。

5. fatigue cracking - 疲劳裂纹，表示材料在反复应力作用下容易产生裂纹。

6. impact testing - 冲击测试，用于评估材料的脆性性质，通过测定其抗冲击能力来评估其 brittleness index。

7. fracture toughness - 断裂韧性，表示材料抵抗裂纹扩展的能力，是衡量 brittleness index 的重要指标之一。

8. fracture toughness testing - 断裂韧性测试，用于测量材料的韧性值和 brittleness index。

9. fracture surface - 断裂表面，表示材料断裂时的表面形貌，可以用来评估材料的脆性性质。

10. fracture toughness limit - 断裂韧性极限，表示材料在受到特定应力时能够抵抗裂纹扩展的最大值。

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

常用短语：

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

双语例句：

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.
