The design of compression springs is tied to their intended function and the acceptable levels of deformation and stress that the spring can withstand. Veryst designed and evaluated a standalone simulation application to capture important qualities, such as spring rate, natural frequencies, and estimated fatigue life, for both helical and conical compression springs.
Arrays of impinging fluid jets are an effective design solution for applications requiring large heat transfer rates. This case study demonstrates the ability of computational fluid dynamics (CFD) to predict heat transfer coefficient distributions and guide design choices to improve cooling uniformity.
Some of the most sensational goals in soccer history came from free-kicks and long shots. (Remember Roberto Carlos’ famous 1998 free-kick?) Veryst investigated the effect of friction between ball and boot, the ball’s internal pressure, and ball materials on the ball’s rotational velocity to understand ball/boot interaction.
How does a soft fluidic gripper perform when inflated and how does it interact with its environment? This is a challenging, yet essential, question to the design and integration of soft robotics in the industry. Veryst Engineering developed a finite deformation Abaqus model to study the behavior, performance, and stability of soft fluidic grippers, providing insight to the design and assessment of soft robots and devices.
Veryst can predict the ultimate strength and failure modes of design concepts generated using topology optimization and produced using additive manufacturing. We use advanced finite element analysis (FEA) that accounts for the nonlinear behavior of the material being used to make the part.
During sloshing, liquid exerts a dynamic force on the surrounding vessel, which may cause leakage or damage to the vessel or its supporting structure. We used a mesh-free smoothed particle hydrodynamics (SPH) method to predict liquid sloshing and its effect on the deformation and stresses in a vessel.
Electroosmotic (EO) pumps are driven purely by electric fields and have no moving parts. Cascading EO pumps reduces voltage requirements. Veryst used computational fluid dynamics (CFD) and semi-analytical equivalent circuit theory to analyze the complex behavior of these pumps.
Thermal management is crucially important for battery performance in consumer products, electric vehicles, and grid-level storage systems. In this case study, Veryst used multiphysics simulations to evaluate different thermal management strategies in prismatic and cylindrical battery packs.
Tires experience large, complex deformation during use, and the highly filled rubbers are difficult to model. Veryst designed and calibrated a custom material model to capture the mechanical behavior of the tire to improve the design.
New total joint replacement prostheses often use ultra-high molecular weight polyethylene (UHMWPE) in load bearing components. Design engineers need to understand the stress and strain distributions in order to extend device life.
Veryst developed a diffusion model accounting for the different layers of the human skin in order to predict the drug concentration profile of a transdermal drug delivery process.
Permeation enhancers are used to improve drug delivery through the skin by altering the structure and dynamics of the skin. Veryst developed a finite element model of drug diffusion from an adhesive patch that accounts for the effect of permeation enhancers.
The microelectronics packaging industry relies heavily on adhesive bonding to assemble electronic components. Veryst built a COMSOL Multiphysics model of a thermocompression bonding process to help reduce bonding cycle time by simultaneously optimizing material and process variables.
When would an automotive disc brake need to be replaced? The continuous frictional sliding between two deformable surfaces leads to wear accumulation and ultimately failure of the weakest component. However, wear modeling is not readily available in most finite element codes. Veryst developed a wear model in COMSOL Multiphysics using differential equations for the wear depth based on a modified version of Archard's law.
Veryst has strong acoustic simulation expertise in a wide variety of applications, including medical devices and wearable technology. In many cases, acoustic problems cannot be solved adequately using a single-physics approach, and Veryst has extensive experience in solving multiphysics problems involving acoustics.
