For the efficient development of lightweight structures realistic models for anisotropic materials are necessary.
For quasi-statically loaded anisotropic materials failure models e. g. by PUCK and CUNTZE are available [2, 3].

Alam et al. did finite element analysis on simplified welded joint and used interface element to simulate fatigue crack propagation problem on the interface of two kinds of elastic materials[4].
Step 1 Step 5 Step 10 Step 20 Fig. 2 Stress nephogram of crack propagation Step 15 From Fig.2, tensile stress on the crack tip increased gradually, the stress ellipse of homogeneous material area on the crack tip is compared to the stress ellipse of non-uniform material area on the crack lower end, the contour line is somewhat smoother, because layer board model is used to imitate non-uniform material of the lower end, which makes material properties have discontinuity.

Linear thermal gradients are then assumed for both materials.
This analysis was used to estimate heating and cooling of the workpieces, as well as nugget penetrations in both substrate materials.

The electrochemical corrosion behavior of ultra-supercritical unit waterwall tube material in simulated solution of oxygenated treatment (OT) with different concentration of Cl- and SO42- at room temperature was investigated by electrochemical impedance spectroscopy and Tafel slopes.
The material employed was T23 steel, which has a composition of 0.04-0.10% C, ≤0.50% Si, 0.10-0.60% Mn, ≤0.030% P, ≤0.010% S, 1.90-2.6% Cr, 0.05-0.30% Mo, 0.20-0.30% V, 0.02-0.08% No, ≤0.03% Al, ≤0.03%N, 1.45-1.75%W and Fe as the balance[12].

Two-step method is preparing granulation first then forming the mold, one step method eliminates the granulation, mixes wood power treated by surface modification and plastic powder at a high speed and then be fed by materials to extrusion.
Mix the raw materials by twin-screw extruder, the water and volatile matter discharge from the junction of two exhaust extruders, then feed the material and foaming agent into the hole of the single-strew extruder.
This series system can mix the materials uniformly, strip the moisture and volatile matter effectively, improves the foam morphology and the product surface quality significantly.
Thus it can combine two different materials firmly together as a bridge.
