Ballistics and Mechanical Test Lab

Researcher focus areas

The Ballistics and Mechanical Testing Lab supports a number of researchers and research areas. Currently, three researchers are involved in the Lab's work.

Dr. Clodualdo (Clod) Aranas

Department of Mechanical Engineering, Faculty of Engineering

Dr. Aranas is the Director of the Alloy Design and Materials Testing Research Laboratory (AD-MTRL) in the Department of Mechanical Engineering at the University of New Brunswick. The research laboratory aims to design and develop the next generation and energy-efficient advanced high-strength materials with a positive impact on the environment. His research includes understanding the mechanical properties and deformation behavior of metallic materials.

Dr. Aranas’s research interests include:

  • Thermomechanical processing
  • Mechanical properties and deformation behavior of materials
  • High-speed deformation
  • Phase transformation in metal alloys
  • Corrosion behavior of materials
  • Static and dynamic recrystallization
  • Materials characterization
  • Texture and anisotropy of materials
  • Development of novel alloys
  • Thermodynamics of materials
  • Constitutive modeling of stress behavior of materials
  • Additive manufacturing of metals

Dr. Alan Lloyd

Department of Civil Engineering (Structural Engineering), Faculty of Engineering

Dr. Lloyd’s current research focus includes explosive and impact loads on structures, specifically concerning reinforced concrete and fibre reinforced polymers. His research is conducted experimentally and using analytical tools including multi-physics simulations and simplified single and multi-degree-of-freedom dynamic analysis.

Dr. Lloyd’s research interests include:

  • Extreme loads on structures
  • Explosive and impact resistant structures
  • Plasticity and ultimate capacity of building components
  • Load paths in structures under lateral loads
  • Response of non-structural building elements such as windows, doors, and infill walls to extreme lateral loads
  • Retrofit of existing structures to increase ultimate capacity
  • Experimental testing of structures
  • Numerical modeling using multi-physics simulations

Dr. Gobinda Saha

Department of Mechanical Engineering, Faculty of Engineering

Dr. Saha’s research and innovation focus is tied with industry needs. Over the past 15 years, his work has been oriented to technology development and integration with industries, primarily focusing on clean transportation infrastructure (rail and aviation), high-speed ballistic threat and shock loading mitigation, superior wear-resistant materials development for industrial manufacturing, oil and gas and renewable energy exploration.

Under his leadership, UNB’s Nanocomposites and Mechanics Laboratory has challenged the current metal-based additive manufacturing approach with nanostructured cermet (ceramic-metallic) and biomass derived composite materials. The lab’s work covers the design, synthesis, additive manufacturing, testing and characterization, field trial and recycle of materials, using state-of-the-art high-pressure cold spray and other technologies to give rise to lightweight, high-strength, high-impact-resistant 3D coatings and freeform component development with extended operational lifetimes.

Research interests include:

  • Nanostructured materials synthesis
  • Cold spray additive manufacturing
  • Coatings and 3D architectures
  • Biocomposites
  • Computational modeling

With application focus areas including:

  • Industrial manufacturing
  • Energy exploration, renewable energy and environment
  • Aerospace and defence
  • Wear, erosion, corrosion, high-impact threats
  • Wastewater purification
  • Structural health monitoring
  • Biomedical engineering
