材料的力学性能是材料使用的主要依据。材料受压时的力学性能是抗压材料使用的主要依据。有关材料在受压时的力学性能在任何一本材料力学书里都可以找到,但有关脆性材料在压缩时的破坏形式和破坏机理,在近几年里有一些争论。我们就典型脆性材料铸铁在压缩时的破坏形式和破坏机理,进行了一些理论和试验研 The mechanical properties of materials is the main basis for the use of materials. Mechanical properties of the material under pressure is the main basis for the use of compressive materials. The mechanical properties of the material under compression can be found in any material mechanics book. However, in the recent years there has been some controversy regarding the form of collapse and the failure mechanism of brittle materials during compression. We made a number of theoretical and experimental studies on the failure modes and failure mechanisms of typical brittle cast iron during compression
