Moisture can have damaging effects on electronic packages by inducing hygro-Thermo-mechanical stresses and vapor pressure. Commonly accepted wetness approach for indirect calculation of moisture concentration can yield unrealistic results. Therefore, a direct concentration approach becomes unavoidable. This study presents the Peridynamic Direct Concentration Approach (PDCA) and its implementation in ANSYS, a commercial finite element software. Numerical results show that PDCA provides accurate predictions, and removes the anomalies associated with the wetness approach. Moreover, ANSYS allows the utilization of implicit time integration resulting in significant computational advantages.
