In India, the Public Distribution System (PDS) provides subsidized food grains to about 800 million people; nevertheless, the distribution method is beset by issues like fraud, leakage, human error, and strict shop schedules. There is a need for effective hopper design that serves in Smart ration distribution system ensuring  real time distribution of ration 24/7 in sufficiently large quantity continuously.

The present work focusses on developing  3D model design of hopper suitable to serve real time application of a smart ration distribution system and performing structural analysis on the hopper by using different materials (SS AISI 1035,SS ferritic and Plain Carbon steel ) for different distributed masses (500kg,1000kg and 1500kg).The optimum choice of distributed mass out of the three load capacities  for hopper is 1000 kg which is 8.7% more than its actual capacity of 1095kg.Results from structural analysis showed that stress and strain increases in hopper design with increase in distributed mass which concludes SS AISI 1035 as the optimum material choice due to minimum deformation of 3.836e-08 m observed  at 1000 kg  and yield strength of 2.727e+08 N/m2 which is 20% more than plain carbon steel and 36% more than SS(ferritic) .
