§7-1ConceptsoftheStateofStress

1.一■點的應力狀態：過一■點有無數的截面，

這一點的各個截面上應力情況的集合，稱為這點的應力狀態。

2.單元體：構件內的點的代表物，是包圍被研究點的無限小

的幾何體，常用的是正六面體。

§7-10強度理論概述

§7-10ConceptsofStrengthTheories1.材料的破壞形式:

⑴屈服(2)斷裂：typesoffailureofmaterials:(1)

yieId(2)rupture

2.強度理論：是關于“構件發生強度失效起因”的假說。

theoriesofstrength:someassumptionsaboutthecause

ofthestrengthfailureofmateriaIs.

§7-11四種常用強度理論

§7-11FourCommonUsedStrengthTheories1.最大拉應

力(第一強度)理論：

認為構件的斷裂是由最大拉應力引起的。當最大拉應力達到

單向拉伸的強度極限時，構件就斷了。

theory):

認為構件的斷裂是由最大伸長線應變引起的。當最大伸長線

應變達到單向拉伸試驗下的極限應變時，構件就斷了

theory):

認為構件的屈服是由最大剪應力引起的。當最大剪應力達到

單向拉伸試驗的極限剪應力時，構件就破壞了。

認為構件的屈服是由形狀改變比能引起的。當形狀改變比能

達到單向拉伸試驗屈服時的形狀改變比能時，構件就破壞了。

2.動荷系數：dynamicIoadcoefficient

3.達朗伯原理：處于不平衡狀態的物體，存在慣性力，慣性

力的方向與加速度方向相反，慣性力的數值等于加速度與質

量的乘積。只要在物體上加上慣性力，就可以把動力學問題

在形式上作為靜力學問題來處理，這就是動靜法。
