Hello everyone.<\/p>\n

I am doing simulation of Rigid body analysis of masonry wall in LS DYNA and needs help on how to improve the numerical simulation.<\/p>\n

Wall dimensions<\/strong>: Height of the wall is 4.1m<\/strong>, Length is 1.15m<\/strong>, thickness is 0.35m<\/strong>. During the experiment, the crack height from the base of the wall is 2.501 m. i.e height of bottom wall is 2.501 m and height of top wall is 1.599<\/p>\n

Contact Automatic Surface to Surface <\/strong>was used in a between the two walls interface and between the floor and bottom wall interface. Friction coefficient of 0.7<\/strong> was used.<\/p>\n

Contact Automatic Surface to Surface <\/strong>was used in a between the top wall and top support. Zero friction<\/strong> was used here.<\/p>\n

Uniformly distributed load was assigned on the wall face.<\/p>\n

Material mode<\/strong>l: Top support and Floor (MAT_001) and assigned to Young modulus Elasticity of 40000 MPa<\/p>\n

              Two block walls (MAT_020) and assigned to masonry Young modulus of 4758 MPa<\/p>\n

Numerical result is not matching with the hand calculation (Rigid body Analysis)<\/p>\n

<\/p>\n<\/p>\n
