材料力学四种基本变形对比

Comparison of the Four Basic Deformations in Mechanics of Materials

材料力学是研究物体承载能力的科学,它的任务是保证既安全又经济的前提下,为构件选择合适的材料,确定合理的截面形状和尺寸,建立构件强度、刚度和稳定性的理论基础,提供必要的计算方法。这就要求对构件四种基本变形的有关知识进行对比、分析。

The mechanics of materials is the science researching carrying capacity of object, and its task is, on the premise of en- suring safety and cost-effectiveness, to provide necessary calcu- lating methods for the determination of the reasonable section shape and size and the establishment of theoretical basis for member strength, stiffness and stability, so as to choose appropri- ate materials for components This requires the comparison and analysis of component-related four basic knowledge of deforma-
