Abstract
Calculation of the pipe-base-embankment system as a frictional contact problem
Incoming article date: 10.07.2022The article deals with the solution of the problem of unilateral frictional contact on the example of an arched culvert in the embankment. Unilateral contact is modeled as a linear complementarity problem, which is solved using the Lemke method. The features of solving such problems are shown. A comparison with modern approaches is given, the advantages and disadvantages of the proposed method are indicated.
Keywords: constructive nonlinearity, frictional contact, unilateral constraints, linear complementarity problem, numerical models, finite element method, load increment
