求翻譯:當材料在外力作用下不能產生位移時,它的幾何形狀和尺寸將發生變化,這種形變就稱為應變(Strain)。材料發生形變時內部產生了大小相等但方向相反的反作用力抵抗外力.把分布內力在一點的集度稱為應力(Stress),應力與微面積的乘積即微內力.或物體由于外因(受力、濕度變化等)而變形時,在物體內各部分之間產生相互作用的內力,以抵抗這種外因的作用,并力圖使物體從變形后的位置回復到變形前的位置。是什么意思?![]() ![]() 當材料在外力作用下不能產生位移時,它的幾何形狀和尺寸將發生變化,這種形變就稱為應變(Strain)。材料發生形變時內部產生了大小相等但方向相反的反作用力抵抗外力.把分布內力在一點的集度稱為應力(Stress),應力與微面積的乘積即微內力.或物體由于外因(受力、濕度變化等)而變形時,在物體內各部分之間產生相互作用的內力,以抵抗這種外因的作用,并力圖使物體從變形后的位置回復到變形前的位置。
