课程名称：材料力学基础 概述：材料力学，又称材料强度学，是研究受力固体物体行为的学科。其理论从一维和二维结构的行为开始，逐步推广到三维，以发展更全面的弹性和塑性材料行为理论。材料力学的研究通常涉及计算结构构件（如梁、柱和轴）中的应力和应变的方法。这些方法考虑了材料的属性，例如屈服强度、极限强度、杨氏模量和泊松比，以预测结构在加载条件下的响应及其对各种失效模式的敏感性。因此，变形体的力学更关注内部 forces 及相关几何形状的变化，因此，材料力学或材料强度学是工程设计活动的核心。分析的主要目标通常是确定加载产生的应力、应变和挠度。理论分析和实验结果在该领域同等重要。本课程将重点介绍材料力学的各种基本概念，学习者将通过解决相关教科书中的数值题来应用这些概念。
Mechanics of Materials, also called Strength of materials, is a subject which deals with the behavior of solid objects subject to stresses and strains. The complete theory began with the consideration of the behavior of one and two dimensional members of structures, whose states of stress can be approximated as two dimensional, and then generalized to three dimensional to develop a more complete theory of the elastic and plastic behavior of materials. The study of Mechanics of materials often refers to various methods of calculating the stresses and strains in structural members such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading conditions and its susceptibility to various failure modes takes into account the properties of materials such as its yield strength, ultimate strength, Young's modulus, and Poisson's ratio. it is also being known as Mechanics of Deformable bodies. The mechanics of deformable solids is more concerned with the internal forces and associated changes in the geometry of the components involved. Therefore, the subject of mechanics of materials or strength of materials is central to the whole activity of engineering design. Usually the objectives in analysis here will be the determination of the stresses, strains, and deflections produced by loads. Theoretical analyses and experimental results have an equal roles in this field.In this course the various fundamental concepts of Mechanics of Materials is been focused. the learner will have to use these concepts by solving the numerical from various books on these subject.
