The elastic and plastic deformation characteristics of magnesium forgings of construction machinery are the important content of studying the deformation behavior of the material under stress. The following is the study of elastic and plastic deformation characteristics of magnesium forgings of construction machinery:
- Elastic deformation characteristics:
Elastic deformation refers to the reversible deformation of the material after the application of external forces, that is, the material can return to its original shape after the removal of external forces. For magnesium forgings of construction machinery, the elastic deformation is affected by the elastic modulus of the material itself, the structure of the material and the Coriolis hardness. The elastic deformation characteristics of magnesium forgings can be studied by experiment and numerical simulation, and the stress-strain curve, elastic modulus and Poisson’s ratio can be obtained. - Plastic deformation characteristics:
Plastic deformation refers to the irreversible deformation of the material after the application of external forces, that is, after the removal of external forces cannot be fully restored to the original shape. For magnesium forgings of construction machinery, the plastic deformation behavior is affected by the yield strength, elongation, hardening behavior and other factors. The plastic deformation characteristics of magnesium forgings, including yield strength, fracture strain and stress-strain curve shape, can be studied by experiment and numerical simulation. - Research methods:
The following methods can be used to study the elastic and plastic deformation characteristics of magnesium forgings of construction machinery:
- Experimental test: Through tensile test, compression test, shear test and other experimental means, the stress and strain of magnesium forgings under different loading conditions are measured, and its elastic and plastic deformation characteristics are obtained.
- Numerical simulation: Using finite element analysis and other numerical simulation methods, simulate the stress situation of materials, predict and analyze the stress distribution, deformation and the formation and development process of plastic zone of magnesium forgings of construction machinery.
By studying the elastic and plastic deformation characteristics of magnesium forgings of construction machinery, the stress response and deformation behavior of magnesium forgings can be deeply understood, which provides a basis for engineering design and manufacturing, and ensures that magnesium forgings have good reliability and working performance.
