| Abstract: | There exists many kinds of calculation models of plane and spherical strain fields, but the results are different.It is analyzed the representative models, and points out which model has unbias as well as which one has deviation,which models deviation can be corrected as well as which one can only be used to the strain computing of uniform medium but can not be extended and which model can be used the calculation and analysis of continuous strain field. Besides, it’s also provides the correction relationship for computing spherical difference movement (displacement) by strain results, and demonstrates the meaning of the non differential term in spherical strain model. |
