NAFEMS LE1 plane-stress benchmark, Gmsh&GetDP

Описание: This problem is known as the NAFEMS LE1 plane-stress benchmark and has been introduced in 1986 as the first problem of The Standard NAFEMS Benchmarks (Test LE1 from NAFEMS Publication NNB, Rev. 3, NAFEMS Linear Benchmarks, 5 Oct 1990.).
The problem consists of a plane-stress membrane defined by two ellipses. The membrane subject to a tension traction condition p=10 MPa on its outermost edge. Due to symmetry, only one quarter of the membrane needs to be modeled. Material’s Young modulus is E=210 GPa and Poisson’s ratio is ν=0.3. The objective is to compute the normal stress in the y direction at the lower inside corner D=(2 m, 0).
The reference solution given in the original NAFEMS book is σy=92.7 MPa.
