"Brittle fracture" 指的是一种脆性断裂现象，通常发生在材料受到轻微或微小的外力作用时，由于材料本身的性质不够强韧而导致断裂。这种断裂通常具有突然性和无明显的预兆，如玻璃、陶瓷、塑料等材料在受到外力时容易发生这种断裂。

Title: Experimental Investigation of Brittle Fracture in a Ceramic Material
Introduction:
Brittle fracture is a common phenomenon in materials with low toughness, such as ceramics. This paper presents an experimental investigation into the characteristics of brittle fracture in a ceramic material.
Materials and Methods:
The ceramic material used in this experiment was a type of high-temperature resistant material. The fracture behavior of this material was studied using a variety of testing methods, including mechanical testing, microstructure observation, and fracture toughness measurement.
Results:
The results showed that the ceramic material exhibited brittle fracture under low-load conditions, with no obvious pre-crack or deformation prior to fracture. The fracture surface was smooth and lacked any evidence of plastic deformation.
Discussion:
The brittle nature of this ceramic material was attributed to its low toughness and high modulus of elasticity. The experimental results provide valuable information for the design and optimization of materials with improved toughness.
Conclusion:
This experimental investigation into brittle fracture in a ceramic material has provided valuable insights into the characteristics of this phenomenon and has implications for the development of more ductile materials.

"Brittle fracture"是指脆性断裂，一种在材料受到较小应力或应变时发生的断裂类型。它通常发生在那些强度高但韧性差的材料中，如玻璃、陶瓷、塑料等。
在英文范文方面，如果您需要关于brittle fracture的更多信息，我建议您查阅相关的科技论文、报告或书籍，以获取更具体和详细的信息。这些资源通常会提供关于brittle fracture的机理、影响因素、应用场景等方面的深入讨论。
“brittle fracture”的意思是脆性断裂。
在英文范文中的具体用法和最新变化，需要具体看语境。如果是工程材料，则表示材料断裂时，材料内部脆性应力状态无法有效吸收裂纹扩展所需的能量，裂纹扩展速度远大于材料均匀蠕变，导致材料发生突然断裂。
