Week 5 Sphere pressing on a plate

OBJECTIVES :-

To find out plastic deformation in structural steel plate while it pressed with sphere

PROCEDURE:-

open the ANSYS WORKBENCH R2
select the static structural analysis
select stuctural steel from list of non linear general materials in engineering data
import geometry
rename its part appropriately
select structural steel for sphere and non linear structural steel for plate
right click model insert symmetry
right click on symmetry insert symmetry regirface on twice ,select its scope and axis for each of them
delete dafult contact in connection and insert manual contact region ,select sphere outer surfacse as contact and plate suraface as target
insert mesh sizing in mesh section and select plate surface and sides as its scope ,input element size as .5 mm
in analysis settings , input number of step as 4 and keep large deflection ON
insert fixed support and select bottom face plate as its scope
insert displacement ,select upper surafce of sphere as its scope , input displacement of 4 mm in y axis through tabular data
in solution section insert directional deformation ,equivalent stress and equivalent stress
select its scope appropriately
run the solve

RESULT :-

DIRECTIONAL DEFORMATION IN Y AXIS :-

EQUIVALENT STRESS IN PLATE :-

EQUIVALENT STRESS IN WHOLE PART :-

EQUIVALENT SRAIN IN SPHERE:-

EQUIVALENT STRAIN IN WHOLE PART :-

TABULATION :-

MATERIAL	DEFORMATION IN Y AXIS (mm)	STRESS IN PLATE(MPa)	STRESS IN WHOLE PART(MPa)	STRAIN IN SPHERE (mm/mm)
strucural steel non linear material for plate	0.33346	3993.6	7852.5	0.039289

CONCLUSION :-

Ship work like this
