Why Pmass?
NOSB-PD
Pmass is built on the most general form of peridynamics, non-ordinary state-based peridynamics (NOSB-PD).
Classical constitutive and damage models
Pmass allows the use of constitutive and damage models from the classical mechanics theory.
Unified Formulation
The peridynamic equation of motion holds true anywhere in a rigid body, despite the presence of cracks and other discontinuities.
Heterogeneous Materials
Pmass allows consideration of highly heterogeneous material constituents and highly complex cracking mechanism.
Complex Material and Cracking Mechanism
Material damage is an inherent feature in Pmass, thus modeling of fracture initiation and propagation, with arbitrary paths, i.e., is permitted without the need for a crack growth treatment.

Model Builder
Pmass supports three methods for creating models for peridynamic analysis: using the built-in Model Builder, importing a CAD model, or importing a finite element (FE) model. The embedded Model Builder allows for the creation of 2D and 3D geometries and the incorporation of voids, cracks, and inclusions within models. Additionally, Pmass streamlines 3D modeling by enabling the direct upload of STL files, a widely used format in 3D printing and CAD. This cloud-based platform enhances stress and failure analyses, improving design accuracy and reliability. Pmass also allows the importation of node positions and element connectivity from existing FE meshes, supporting various element types for 2D and 3D models.

Grid Generator
Pmass' Interactive Grid Generator tool facilitates the discretization of models into peridynamic points. Beyond simply adjusting the spacing between these points, the tool offers various methods of point placement, such as quadrilateral (2D and 3D), circular (2D), spherical (3D), and cylindrical (3D). Additionally, within Pmass, users have the flexibility to express the family of a particular peridynamic point using different available options: rectangle and circle for 2D models; and cuboid, sphere and cylinder for 3D models.

Run Simulation
Pmass is fully implemented on the cloud, leveraging high-performance computing for rapid analysis and efficient resource utilization. This allows users to obtain accurate results much faster than traditional methods. Cloud computing offers cost-effectiveness, ease of maintenance, flexibility, and scalability, making it ideal for peridynamic analysis. Pmass takes advantage of these benefits to enable efficient modeling of fracture initiation and propagation without the need for specialized crack growth treatments.

Post Processing
Pmass offers real-time visualization of stress and failure analysis results, allowing engineers to explore 2D and 3D models, inspect crack paths, and analyze critical areas interactively. Customizable reporting features enable clear communication of findings to stakeholders, clients, and regulatory bodies. The embedded post-processing tool lets users visualize results with scatter and line plots. Simulation results can be downloaded as text files for use with various post-processing tools, and comprehensive analysis reports can be downloaded as PDF files.

Stress Analysis
Pmass supports linear static analysis, the most common mechanical engineering analysis. Linear static analysis helps engineers determine the stress and strain distribution within the part when subjected to different loads. This information is crucial for assessing the structural integrity and ensuring that the part can withstand the applied loads without failure.
Validation Cases
Fracture Analysis
Developed based on peridynamic theory, Pmass is a powerful tool for studying failure in engineering parts and structures. Material damage is inherently modeled in Pmass, allowing for the simulation of fracture initiation and propagation along arbitrary paths without requiring specialized crack growth treatments.
Validation Cases
Composite Materials
Pmass supports the modeling and analysis of composite materials. Fiber-reinforced composite laminates can be modeled by assigning orthotropic material properties. Various failure models, including the Hashin criteria, are embedded in Pmass for comprehensive failure analysis. Additionally, Pmass supports the modeling of particle-reinforced composites, making it a versatile tool for analyzing different types of composite materials.
Validation Cases
Quasi-Static Loading
Pmass supports structural and failure analysis under quasi-static loading conditions. Quasi-static loading refers to a type of loading applied over a relatively long period, allowing the material to respond elastically due to the slow changes in loading.
Validation Cases
Transient Loading
Pmass supports structural and failure analysis under transient conditions, also known as dynamic loading. In structural mechanics, dynamic loading refers to the rapid and frequently changing application of loads over a short period of time.
Validation Cases
Hybrid Loading
Pmass supports hybrid loading conditions by combining quasi-static and transient solutions. This approach allows users to perform faster transient analyses by first applying a large quasi-static load up to the failure point, followed by transient loading for dynamic failure analysis.
