AI Technical Summary
When conducting mechanical properties research on multi-layer ceramic dielectric capacitors (MLCCs), the existing technology has problems such as large amount of calculations, excessive number of grids, and inability to converge the calculations, making it difficult to achieve effective quantitative analysis and failure mechanism research.
A multi-layer ceramic dicapacitor cross-scale simulation modeling method is proposed. By extracting the smallest repeating cell body, the equivalent elastic modulus, Poisson's ratio and shear modulus are calculated, and the equivalent material attribute formula set is formed, which is used to establish a cross-scale finite element simulation model.
This method can effectively reduce the time and cost of physical experiments, reduce the difficulty of simulation modeling, improve calculation efficiency, and ensure the accurate calculation results of key areas of attention.
