amplitude of stress 基本释义：应力振幅
发音：英 [??mpl?tju?d ?n ?stres] ； 美 [??mpl?tju?d ɑ?n ?stres]
英语范文：
The amplitude of stress is a measure of the extent to which a stress wave varies in intensity. It is usually expressed in units of force per unit area. When a structure is subjected to a force, it experiences a corresponding stress wave that travels through the structure. The amplitude of this stress wave determines how much deformation or damage occurs in the structure as a result of the force. Therefore, it is important to understand the amplitude of stress in order to predict and prevent structural failure.
音标和基础释义：
amplitude of stress 的音标为 [??mpl?tju?d ?n ?stres] ，意为“应力振幅”。它是一种测量应力波强度变化的程度的方法，通常用单位面积上的力来表示。当一个结构受到力作用时，它会经历一个相应的应力波，这个波的振幅决定了由于力作用而导致的结构变形或损坏的程度。因此，理解应力振幅对于预测和防止结构失效非常重要。
基础释义：应力振幅指的是应力波强度变化的程度，通常用单位面积上的力来表示。它决定了结构受到力作用后变形或损坏的程度，因此理解应力振幅对于预测和防止结构失效至关重要。

标题：一个桥梁的重生
在我家乡的那座老旧桥梁，承载着无数人的回忆。然而，随着时间的推移，它开始经历应力幅度增大的问题。起初，这个问题并不明显，但随着交通量的增加，它逐渐变得明显。桥梁的护栏开始出现裂痕，桥墩也开始摇晃。
我亲眼见证了这座桥梁的衰落，我开始思考amplitude of stress的含义。它不仅仅是一个数学概念，更是一个警示，提醒我们关注生活中的压力和负担。这座桥梁就像是我们生活中的许多事物，如果我们不注意压力的积累，那么最终可能会导致灾难性的后果。
幸运的是，我们的政府和工程师们意识到了这个问题，他们开始采取措施来解决这个问题。他们采用了先进的科技，测量了桥梁的应力幅度，并采取了相应的加固措施。经过一段时间的努力，他们成功地恢复了桥梁的稳定性和安全性。
这个故事告诉我们，我们必须时刻关注生活中的压力和负担，并采取适当的措施来应对它们。只有这样，我们才能避免像那座老旧桥梁一样的悲剧发生。让我们一起努力，创造一个更安全、更健康的生活环境。

amplitude of stress
The amplitude of stress refers to the range of stress values in a given material. It is important in determining the mechanical properties of a material, as it affects the strength, ductility, and toughness of the material.
In engineering design, it is essential to understand the amplitude of stress that a structure or component may experience. If the amplitude is large enough to exceed the material's strength, it can lead to structural failure and potentially dangerous situations. Therefore, it is necessary to carefully consider the loading conditions and design the structure or component accordingly.
In addition to structural design, the amplitude of stress also affects the selection of materials. For example, certain materials may have a higher strength-to-weight ratio, making them more suitable for use in lightweight structures that experience high amplitude loads.
On a more fundamental level, the study of amplitude of stress is also important in understanding material behavior under various loading conditions. Understanding these relationships can help us develop more accurate predictions of material behavior under different loading conditions, which can have a significant impact on engineering design and optimization.
In summary, the amplitude of stress is an important concept in mechanical engineering that affects the design and selection of materials, as well as the safety and performance of structures and components. Understanding this concept is essential for effective engineering design and optimization.

Exercise: Design a Structural System for a Building Undergoing Cyclic Loading
As an example, consider designing a structural system for a building that undergoes cyclic loading. The building may experience different forces at different times, resulting in different amplitudes of stress on different parts of the structure. Your task is to design a system that can withstand these varying forces while maintaining its structural integrity.
Solution:
1. Identify the different forces that may act on the structure, including wind loads, seismic loads, and dynamic loads due to traffic or other sources.
2. Determine the amplitude of each force and its corresponding stress on different parts of the structure.
3. Select materials and components that have appropriate strength and ductility for each part of the structure based on its expected amplitude of stress.
4. Design the system to accommodate for varying forces by using appropriate connections and reinforcements between components and between different parts of the structure.
5. Test and validate the system using simulation software to ensure it can withstand the expected cyclic loading while maintaining its structural integrity.
