|compressive strength/compression strength;抗壓強度;壓應力;抗壓力;壓電阻
"Compressive resistance"(抗壓強度)是材料力學中的核心概念,指材料或結構在承受軸向壓力時抵抗形變和破壞的能力。該指标通過最大壓應力值量化,單位為兆帕(MPa)或磅力每平方英寸(psi),計算公式為:
$$ sigma_c = frac{F}{A} $$
其中$sigma_c$為抗壓強度,$F$為破壞載荷,$A$為材料原始橫截面積。
在工程實踐中,抗壓強度是評估混凝土(根據美國混凝土協會ACI 318标準)、金屬(參照ASTM E9測試規範)和岩土材料(依據ISRM建議方法)的重要參數。例如,C30等級混凝土的抗壓強度需達到30 MPa,這一數據被廣泛用于建築基礎設計和橋梁樁基計算。
材料科學領域的研究表明,晶體結構缺陷會顯著降低金屬材料的抗壓強度,相關機理在《Materials Science and Engineering》期刊的多篇論文中均有詳細論述。土木工程師應用這些理論時,通常會結合國際标準化組織(ISO 12135)的測試流程來确保數據可靠性。
“Compressive resistance”是工程和材料科學領域的術語,指材料或結構在承受壓縮力時抵抗變形或破壞的能力。以下是詳細解釋:
詞義拆解
專業定義 該術語通常等同于抗壓強度(compressive strength),即材料在受壓失效前能承受的最大應力值。計算公式為: $$ sigma_c = frac{F}{A} $$ 其中 $sigma_c$ 為抗壓強度,$F$ 為破壞載荷,$A$ 為受力截面積。

示例:混凝土的compressive resistance越高,越適合用于承重柱等結構。如需更全面的工程參數,可參考材料力學手冊或專業檢測報告。
