摘要：

A simple elastic model for residual stresses and shrinkage of a thin solidifying product is proposed. The model results in expressions ready to be used. It accounts for shrinkage anisotropy between in-plane and thickness directions, caused by different constraints in deformation. The model uses local values for temperature, pressure, crystallization, and (if present) extent of reaction, which belong to the standard output of most simulation codes. It is therefore assumed to be valid also for complex shaped products.
