The compatibility of deformation may occur on tube thread according to dimension of collar thread, which is helpful in improving the connection quality.

Discussion of the forming mechanism of reflective cracks in pavement from the angle of deformation compatibility;

Phillips's serise/parellel model has been employed, Transverse modulus of squarefibrous composites are analysed from longitudinal deformation compatibility, Then, by virture of relative volume fraction application are discuss for a wide range of fire section.

According to the deformation compatibility relationship between corroded steel bars and concrete,on the basis of the constitutive relationship which can reflect the mechanical properties of corroded steel bars and concrete respectively and the bond-slip constitutive law,a nonlinear differential equation for the beam,expressed in the form of the tensile force(N) o.

Method for calculating settlement of composite ground under rigid foundation considering distortion coordination;

Based on the allowable stress theory,considering the stress characteristics of reinforcing layer before and after reinforcement,and guaranteeing the reinforcing layer and the original structure distortion coordination as a premise,a equation about reinforcing layer thickness section destruction was established before reinforcement to determine the reasonable thickness of reinforcing layer.
