[문제]
인장을 받는 구멍을 갖는 평판(plate)의 평면 응력 해석을 수행하라.
.단위: mm, N -> MPa
.평판 크기: 40 x 40 mm
.구멍 반경: 2.5 mm
.내압: 15MPa
.재료: 강재(200,000MPa, nu=0.3)

(1) Part
.Create Part
 -Pipe, 2D Planar, Deformable, Shell, 50
 -파이프 단면의 1/4을 작성
 -Hole 만들기: Shape > Cut > Extrude

(2) Property
.Create Material 
 -Steel: E=200000, nu=0.3
.Create Section
 -Planar, Solid(Default: 단위 폭), Homogeneous w/ Steel
.Assign Section

(3) Assembly
.Create Instance
 -part를 instance(실체)로 작성, Independent(mesh on instance)
 

(4) Step
.Create Step:
 -Step-1: Static, General -> Basic(Large defor, NL) -> Increment size(1000, 0.51)

(5) Interaction: 건너 뜀

(6) Load
.Crete Load
 -Load-1: Pressure|Uniform|-1
.Crete BC
 -BC-1: Mechanical|Symmetry/... ~ 수평방향 롤러
 -BC-2: Mechanical|Symmetry/... ~ 수직방향 롤러

(7) Mesh
.Obeject: Assembly선택
.Assign Mesh Controls: Quad; Structured
.Assign Element Type: Plane Stress
 (Note: Plane Strain이 아닌 Plane Stress를 선정)

.Seed Part Instanc: Global Seeds
 -Approximate global size(1)
  
.Mesh Part Instance

(8) Job
.Create Job: HolePlate
