The accuracy of a new integration algorithm is examined for a von Mises-type model of thermal-elastic-plasticity with nonlinear, mixed isotropic-kinematic hardening. The algorithm is founded on the frame of an integral representation of the conventional rate constitutive equations in contrast to the conventional rate equations themselves. The thermal effect on the yield surface is built in this approach without any difficulty. Under a generalized assumption of a constant strain rate, the model can be reduced to two scalar first-order ordinary differential equations which make an error-controllable integration method possible. Furthermore, for a nonconstant strain rate, e.g., a linear strain rate, the same idea of derivation achieves a similar conclusion. Errors of single-step stress predictions for given total strain increments are discussed.
With the rapid development of the times, new tools are constantly appearing in visual communication design, such as the use of graphic creativity in visual communication. With this as a starting point, this paper introduces the MOEA/D algorithm, which decomposes the MOP problem into a series of subproblems to be solved by decomposition techniques, using weight vectors to obtain the neighbors of each subproblem, followed by calculating the neighbor subproblems, dividing the individuals into segments, and obtaining the child individuals. Finally, the fitness of each offspring individual was calculated and cut to give the final level of each factor. Finally, the strategy of using graphic creativity in visual communication design in the context of Internet+ is calculated from the MOEA/D algorithm. The experimental results showed that by means of multiple control groups, the experimental group achieved a 30% correct rate for Q3 and Q9 quiz questions, and the experimental group had a significantly greater correct rate than the control group. Therefore, more design concepts and design thinking can be explored through the study and analysis of graphic creativity to help the use of graphic creativity in the work of visual communication design.
