In the homogeneous model, the function of tendons is assumed to be uniform in some approximated way in order to form an equivalent homogeneous material within concrete. The formulation of the homogeneous model is same with that of general FEM for common continuum, let alone the elastic matrix being resultant of that of tendon and concrete. The computation is simple, but the approximate assumption makes this method cannot be generalized, because it only represents the constitution and function of tendons in such a rough way, that the numerical results are inaccurate. In the combined model, the function of tendon is considered by the stiffness matrix with rod element, then add it into the stiffness matrix of concrete by a rational way.

均匀类单元是设想将钢筋均匀弥散于整个单元中，使其成为一种连续均匀材料单元，这种单元的与一般有限元的单元刚度矩阵推导过程一样，只不过其弹性矩阵由混凝土和钢筋两部迭加而成的，此类单元刚阵计算简明而又不会扩大计算规模，但均匀弥散只是为计算简单而作一种假想，不贴近单元构造实际，也不符合实际作用效果。

The metal mold design now adopt a form of one mole but six cayities ,this way can improve the efficiency;the mold's joint face is the ball's neutral plane,that makes the mold opened convenient;In the gating,the runner and the riser is the same ,and this design adopt scum riser,that make sure a better routing and make sure the casting's feeding;the mold use gravity to lockwasher itself;the core's material is quartz sand,and spread high tempearature resistant dope on it;In the design, same taper in the guide bush of the core box is needed to make sure open the mold easily;The insert blocks of the core box are made by numercial control processing,this way reduce the cost of production; the scale division positioner make sure the same specification has better interchangeability,also,as all the machining can be finished on the general machine tool,it make the cost low,so it can be spreaded abundant in the medium and minor enterprise;when workout the mold's processing technology,this design adopt the rough's two end plane as benchmark,the ball cavities are machined by scale division positioner;then use Autocad,Pro/e to draw planar and three dimension blueprint,use Pro/e to make three-dimensional animation.
