# Finite Element modeling

Hello Everyone

I am trying to simulate material dumping process from shovel onto mining dump truck. And for that i am using Abaqus/Explicit.  When i plot the contact force of material falling onto truck body under gravity, it gives me the maximum value of 0.12e+11, where as a simple theoretical analysis shows that the resulting impact force for 100 tons of material falling under gravity should be 9e5 N. I am not been able to understand the reason that why Abaqus /Explicit is exaggerating the impact/contact force so much. And i dont know how to correct this thing.

Diabetic foot represents a complication of diabetes that can lead to foot ulcers and other serious conditions. 3D Finite Element (FE) analysis enables dynamic characterisation of different loads within the foot.

This study developed a subject-specific 3D FE model of a diabetic neuropathic and a healthy subject’s foot from MRI data. Experimental analysis of the biomechanics of the foot was combined with FE simulations of foot models generated in Simpleware software.

Hi,

I have modeling a ground in abaqus and simulated earthquake. will i need allow infinite elements in the laterals model (left and right). In other examples i see in the features (module part) created  "shell planar" en the places to create the infinite element (edge, no plane)... so .. how its made ?

thanks. 

PD: Me english is terrible, sorry.

Several models have been developed over the past decades to capture the fracture and failure of ceramic materials. JH2, JHB models are widely used for simulating the behavior of armor plates upon ballistic impact. I have a doubt regarding these models. Are these models only valid when the impact velocity is in the order of 1000m/s, as under such circumstances material transitions from elastic to elastic-plastic regime defined by the HEL Pressure? But what about when the impact velocity of the ceramic is around 300-400 m/s (a fraction of ballistic impact)?
