The application of DQEM to the analysis of the influence of axially distributed force on the deformation of a Timosheko beam is carried out . The approach uses the differential quadrate (DQ) to discrete the governing differential equations defined on all elements , the transition conditions defined on the inter-element boundaries of two adjacent elements , and the boundary conditions of the beam . By assembling all the discrete relation equations , a global linear algebraic system can be obtained .
The numerical procedure of this method can be systematically implemented into a computer program . The coupling of solution at discrete points is strong . In addition , all fundamental relations are considered in constructing the overall discrete algebraic system .
DQEM is a highly accurate analysis method . By using this method , error can be effectively reduced and convergence can be improved . Consequently , the CPU-time required can be drastically reduced .
