Abstract. In this work we will consider a simply supported square plate of side L that is subjected to a load q per unit area. The deflection w in the z-direction is the solution of the Poisson differential equation. For simplicity, we suppose that the loading is uniform so that q is constant. The program is written for computing the deflections w at a set of points with n intervals along each side of the square plate. In this case, we employ a program that uses the Gauss-Seidel method to approximate the solution of Poisson's equation. The program is written for kmax applications through all interior grid points.
Key words:  Square plate, uniform load, deflection, program, Poisson's equation, Gauss-Seidel method, grid

PROGRAM ZA PRORAČUN  DEFORMACIJA KVADRATNE PLOČE OPTEREĆENE JEDNAKOPODELJENIM OPTEREĆENJEM 
POMOĆU GAUS-SAJDELOVE METODE ZA SLUČAJ POASONOVE DIFERENCIJALNE JEDNAČINE
U ovom radu se razmatra slobodno oslonjena kvadratna ploča stranice L opterećena opterećenjem q prko cele površine. Pomeranje w u z-pravcuje je rezultat poasonove diferencijalne jednačine. Pretpostavlja se da je opterćenje q konstantno. Program je napisan za proračun pomeranja w za skup tačaka u n intervalu duž svake strane kvadratne ploče. U tom slučaju se koristi program sa Gaus-Sajdelovom metodom za aproksimaciju Poasonove diferencijalne jednačine. Program je pisan za kmax za sve tačke u unutrašnjoj mreži.
