In order to effectively describe the progressively intralaminar and interlaminar damage for composite laminates, a three-dimensional progressive damage model for composite laminates to be used for low-velocity impact is presented. it is based on continuum damage mechanics (CDM) and was developed and implemented in the user subroutine of ABAQUS explicit, VUMAT. the nonlinear damage model can be used to analyze the dynamic performance of the composite structure and its failure behavior. For the intralaminar damage, as a function of the energy release rate, the damage model in an exponential function can describe the progressive development of the damage. VUMAT subroutine is validated by well-known papers and can be used in any simulation.

Abaqus Explicit-Damage initiation by Abaqus Hashin criterion

abaqus explicit

3D Hashin Failure criterion is not supported in abaqus explicit for solid elements. The Hashin damage initiation criterion must be used with elements with a plane stress formulation, which includes plane stress, shell, continuum shell, and membrane elements. so it is not used for 3D solid elements. It is often necessary to use 3D solid elements (For example C3D8R) in simulating the damage of FRP composite materials with an explicit solver. So what is the solution?

The Abaqus anisotropic damage model for unidirectional fiber-reinforced composite is based on the work of Matzenmiller et al. (1995), Hashin and Rotem (1973), Hashin (1980), and Camanho and Davila (2002).

Four different modes of failure are considered:

fiber rupture in tension;
fiber buckling and kinking in compression;
matrix cracking under transverse tension and shearing; and
matrix crushing under transverse compression and shearing.

Damage evolution for fiber-reinforced composites in Abaqus

it is based on energy dissipation during the damage process and is linear. in the following table, you can find the differences between Abaqus built-in Hashin model and the 3D Hashin VUMAT subroutine.

	Abaqus built-in Hashin	3D Hashin VUMAT Subroutine
Elements	Plane stress, shell, continuum shell, and membrane elements	Three-dimensional solid element
Damage Initiation	Hashin and Rotem (1973), Hashin (1980)	Hashin (1980) and Maximum stress criteria
Damage Evolution	Linear	Exponential (based on Linde (2004))

Mesh sensitivity

The energy dissipation and characteristic length are introduced into the damage evolution law to reduce the mesh sensitivity

Damage variables

7 damage variables to see every mode of failure

Shear modes

It is based on the maximum stress criterion. Also, shear stiffness loss due to the matrix failure under loading is investigated.
