Elmod® 6 FEM / LET / MET Module
|
Three modules can be included with Elmod® 6. They can be accessed through the Elmod interface and function as fully integrated parts of Elmod ®.

The FEM (Finite Element Module) makes use of an axial symmetric finite element program. The LET (Linear Elastic Theory) option makes use of the Waterways Experiment Station’s program (WESLEA), and MET is similar to the method used in ELMOD with improved adjustment factors
The program can be used to manually change the layer moduli (or other parameters) and compare the effect on the deflections. An automatic fitting of measured and calculated basins may also be done, either on a point-by-point basis or for all points in the FWD file. With FEM all of the layers may be treated as non-linear elastic, and with MET the subgrade may be non-linear. Both LET and MET may determine the depth to bedrock. The program may also be used to calculate the critical stresses and strains at the layer interfaces
