|compression deformation/compressive strain;压缩变形；压缩形变
压缩变形（compressive deformation）是指材料或结构在受到外部压力作用时，其形状或体积发生不可逆改变的现象。该术语在材料科学、土木工程和机械制造领域具有重要应用价值。
从物理机制分析，压缩变形包含两个阶段：弹性变形阶段中材料会随压力消除恢复原状，而塑性变形阶段则会产生永久形变。根据胡克定律，在弹性阶段应力（σ）与应变（ε）呈线性关系，公式表示为： $$ σ = Eε $$ 其中E为弹性模量，该参数是衡量材料抗压能力的关键指标。
在工程实践中，中国国家标准GB/T 7314-2017《金属材料 室温压缩试验方法》明确规定了压缩变形的标准化测试流程。美国材料试验协会ASTM E9标准则详细描述了不同材料的压缩性能评价体系。
