Fea Analysis

Additive manufacturing (AM) techniques can help to reduce the time and cost for manufacturing complex shaped parts. The main goal of this research was to determine the best strength structure of six different types of lattice cells, manufactured using the Poly Jet AM technology. In order to perform the tests, six samples with the same structure were created for each lattice type. For testing the samples in compression, an electromechanical test machine was used. finite element analysis (FEA) analysis was used in order to determine the area where the greatest stresses occured and to estimate the maximal compressive strength. The strongest structure was determined by obtaining the maximal compressive strength. This was calculated in two ways: as a ratio between the maximal supported force and the mass of the sample (N/g) and as a ratio between the maximal supported force and the critical section of the sample (MPa).

The Finite Element Analysis

Charpy impact test is very sensitive to mechanical processing technologies and product defects. Charpy impact test can give quantitative test data and improve the product quality of advanced manufacturing industry and the safety of the application of new materials. The Charpy impact test machine has elastic deformation. The center of percussion is different from the designed center of strike and this difference can affect the vibration energy on the pendulum. In this article, by using the finite element analysis method, we simulate experimental processes having different distance to the center of percussion and obtain the numerical quantity related effects. In the end, we verify the accuracy of the finite element analysis by using different energy level impact test.

Good Agreement

The solid modeling method for Expandable Polyethylene (EPE) and honeycomb paperboard combination structure was studied. The static compression of the structure was simulated by finite element method (FEM). The effect of the thickness of the EPE on the structure was analyzed, and the stress distribution and deformation characteristics were obtained. The results showed that the thickness of EPE had no significant effect on the yield stress of the structure, but the corresponding strain was increased with the increase of the thickness of EPE. The EPE could protect honeycomb paperboard from damage. The results of finite element analysis were in good agreement with the experimental results.

Echelle Grating

For the research on elastic-plastic deformation characteristics of the echelle grating in the mechanical ruling depth range, a series of nanoindentation tests are completed about the deposited Al film of available echelle grating with a Berkovich indenter on a CSM nanoindentation instrument. Then a finite element analysis of the nanoindentation process is studied with an orthogonal experiment method for a series of given parameters containing the yield stress and strain-hardening exponent. The optimum combinations of yield stress and strain-hardening exponent are 200MPa and 0.1, which are got by the objective of the least absolute value of maximum loads deviation between the indentation test and the finite element analysis. Finally the elastic-plastic stress-strain curve of power function of the Al film is represented with the difference analysis from the orthogonal simulations.
