The color of ceramic particles is bright and the appearance is beautiful. It is a new material currently available in the market for constructing landscape residential areas in urban areas and beautifying the urban environment. What is the method to prevent these particles from wrinkling? Here is the editor's summary:
1. Stress criterion for ceramic particles: If the principal stress is 20, the membrane unit is stretched; If 20, fold the membrane element; If 10, the element is relaxed.
If the strain criterion is 20, the membrane unit is stretched; If 20 and 10, the membrane element wrinkles; If 10, the element is relaxed.
In load analysis, all units are distinguished one by one at each step of load increment. If wrinkled units are found, they can be processed as follows:
1. Ceramic particle modification of unit stiffness: to reduce the contribution of folding units to the overall stiffness of the structure, that is, to modify the stiffness matrix of folding units, thereby reducing their actual load sharing and increasing the burden on adjacent units.
2. Ceramic particle modification of structural stiffness: Return to the shape finding stage to modify the surface, that is, by modifying the boundary conditions of local areas or adjusting the prestress to modify the structural stiffness.
Ceramic particles have good wear resistance and are specifically used in harsh outdoor environments. They will not change color after long-term use. I hope the above content is helpful to you.
