This process, called creep, is affected by rheological properties of substances.
Delayed inelastic strain is explained by the viscous properties of concrete [1].
Factors as the influence of the environment, aging of concrete under load, impact dimensions of the elements, consistency of concrete, type of cement and gravel aggregates, temperature and concrete curing; affect the rate of creep to varying degrees and therefore they are relevant for the calculation of creep.
Here the factors affecting creep over time using coefficients have been considered.
In more precise calculations it is necessary to consider the factors influencing creep.

Comprehensive evaluation is a method to make overall evaluation of an object influenced by multi-factors.

The filling and solidification process can be studied qualitatively and semi quantitatively by computer numerical simulation technology without restriction on the experimental condition, various influencing factors of the casting defect can be found and analyzed, it is significant to both the development of LFC process theory and the guidance of practical production [3, 4, 5].
The mainly influencing factors of filling and solidification process of LFC are given in figure 2: (1) The gas evolution and chemical reaction of different density of the foam pattern materials are diverse. (2) The air permeability and strength of the coating is vital. (3) The quality of the castings would be affected by different pouring way, sprue-runner-gate area ratio, pouring rate and pouring temperature. (4) Also the vacuum degree, the breathability of the molding sand and the molten metal material are crucial. 3D modeling Influencing factors Meshing Disqualified Checking Casting material Molding sand Vacuum degree Gating system Coating Foam material Qualified Parameter setting Sprue-runner-gate area ratio Pouring temperature Pouring rate Pouring way Computation Results Fig. 1 Simulation flow chart Fig. 2 Influencing factors of LFC simulation The fundamental key points of an effective numerical simulation of LFC
How different alloy materials, pouring system affect the filling and solidification process of LFC and how to choose the optimum casting parameters were given by J.H.
Because of the coexistent of liquid and solid metal, the mechanical property of the castings is hard to measure during the simulation process and still the proper mechanical model can't be completely established.
