The total irregularity of a simpleis the degree of the vertex u.In this paper we investigate the change of the total irregularity of graphs under various subdivision operations.Also, we present exact expressions and upper bounds on the total irregularity of different composite graphs such as the double graph, the extended double cover of a graph, the generalized thorn graph, several variants of subdivision corona graphs, and the hierarchical product graphs.
