Week 10 Bullet penetrating a Bucket Challenge

Explicit dynamics simulation of bullet penetrating through bucket is given as follows:

The above simulation is sub divided in three different material properties of bucket viz:

i) Al-1100

ii)Gold

iii)Platinum

CASE1: Al-1100

GEOMETRY:

MESH:

Fig.Mesh Generation

Fig. Element Quality

Fig.Skewness

From the above mesh condition the Elemet qualtiy appears to be 0.62 with edge sizing of 4mm at the point where bullet is going to penetrate the bucket and number of elements corresponding to 8962

BOUNDARY CONDITIONS:

Fig. Von Mises Stress For Case iii

Sr.No	CASE	MATERIAL	Total Deformation(mm)	Von Mises Stress(MPa)
1	CASE i	Al-1100	540.87	122.73
2	CASE ii	GOLD	1791.1	101.87
3	CASE iii	PLATINUM	1218.6	93.048

From the above tabulated data it is clear that gold has higher deformation of magnitude 1791.1mm and max stress generated 122.73MPa respectively.While the lowest deformation of Al-1100 and lowest stress of 93.048 MPa
