Hi everyone,<\/p>\n

I’m running drop test simulations on explicit dynamics in workbench. I’m simulation an apple falling from a drop height of 2 meters under standard earth gravity. I want to simulate the deformation once the apple lands on the rigid surface.<\/p>\n

Here are some the challenges I’m facing:<\/p>\n

1. An apple is not a perfect sphere. How do I include some physical and mechanical properties of the apple e.g.
~Equatorial diameter
~Polar diameter
~Thickness
~Shape index
~Volume
~Curvature radius<\/p>\n

2. I assumed a perfect sphere for the initial simulations. However, the apple bounced off the rigid structural steel surface like a tennis ball would. How can I overcome this and effectively realize a simulation that depicts normal reaction of the apple in such a scenario<\/p>\n

3. Change in color depicts change in deformation to a varying extent. However, there is change before the apple hits the surface. What could be the issue and how can I overcome it.<\/p>\n","protected":false},"template":"","class_list":["post-358681","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
