description The invention provides a GPU parallel two-dimensional particle discontinuous deformation analysis method and device, a medium and equipment, and belongs to the technical field of computer program virtual reality simulation. The method comprises the following steps: establishing a two-dimensional particle discretization model to be analyzed, material attributes and control parameter information; transmitting the to-be-analyzed two-dimensional particle discretization model, the material attributes and the control parameter information data to a GPU (Graphic Processing Unit); performing contact pair retrieval to obtain the two-dimensional particle contact pair to be analyzed and a contact state; a non-contact force stiffness matrix is assembled according to the minimum potential energy principle; aiming at the contact state of the two-dimensional particle contact pair to be analyzed, assembling a contact force stiffness matrix according to a minimum potential energy principle; an overall equation is established
