Hello all,
I am learning to write an ABAQUS VUMAT subroutine for Deshpande Evans (DE)/ Preston-Tonks-Wallace Material (PTW)constitutive model. I didn't write a subroutine before. I would appreciate any guidance toward the development of a subroutine. If anyone can share a VUMAT subroutine for...
Assume the nanoparticles are in spherical shape and distributed uniformly/randomly in a matrix composite (as shown in the image below). Moreover the nanoparticles are transversely isotropic crystal and the matrix is isotropic polymer. Then what would be the effective properties of the composite...
I apologize if my question was ambiguous. Let me break it down.
Suppose I have a polymer fiber-reinforced composite. Now the effective elastic properties of this composite will be anisotropic which means I will need 21 coefficient (C[sub]ijkl) of the elastic stiffness matrix for this composite...
Hello,
I have a unit cell composed of piezoelectric particle and non-piezoelectric polymer matrix as shown in the image below. I want to calculate the EFLX (Electric flux density) vector. I am using Abaqus. I have used 3D stress element for the matrix and piezoelectric element C3D4E for the...
