The traditional analogy method based on experience is insufficient for large and complex ram; it is difficult to have a reasonable distribution of materials, so the potential of the materials is unable to be fully exerted.
According to the strength, stiffness and precision requirements of the ram structure and ram materials’ mechanical properties, the state variables of the ram were confirmed.

E309Nb welding rod, ER310 welding wire, and ER309L welding wire were used as cladding filling materials, and ER50-6 welding wire was used as base-layer filling material.
Impact properties of Q345R/304 welded joints.The impact test is used to measure the impact toughness of materials.
The impact work describes the sensibility of materials to notch or crack under the dynamic load condition.
The welding joints were divided into three groups A, B and C, and corresponding welding materials are E309Nb, ER310 and ER309L respectively.

Corn is the main raw material for fuel ethanol in China.
Development of fuel ethanol industry expands the market of agricultural products for demand of raw materials.
Theoretical Model Corn is one of the foods in family life, and is also the raw material for production of fuel ethanol, so there is conflict between food and fuel ethanol.

The second timber element previously prepared as the first one is positioned and finally, the whole packet is pressed for obtaining the optimal contact between materials, as showed in Fig.1.
Choosing these materials was based on the composite nature of both ones, reinforced with long fibers.
In this portion of the diagram, the deformations are unitary, but the materials overtake the loads in different proportions.
