Abstract. Pressure distribution in elastic concentrated contacts is solved using a modified influence coefficient method. The iterate process starts with a lower than expected estimated domain, which is extended, in relation to contact geometry, until the static force condition is verified. This approach reduces the dimensions of the systems to be solved in pressure, but their number generally increases. In some cases, the method is more efficient than the classical one in computational time, while the precision is preserved.
